Texto completoThis research deals with wireless multi-radio transmitter architectures operating in the frequency band of 800 MHz – 6GHz. As a consequence of the constant evolution in the communication systems, the mobile transmitters must be able to operate at different frequency bands and modes according to existing standards specifications. The concept of a unique multi-radio architecture is an evolution of the multi-standard transceiver characterized by a parallelization of circuits for each standard. Multi-radio concept optimizes surface and power consumption. This study concentrates on flexible multi-radio architectures. This kind of architectures could be used in the future for cognitive radio applications. The power amplifier (PA) is the key element in transmitter architectures. Its operating principle establishes a trade-off between power efficiency and linearity. The utilization of a switched mode amplifier allows improving efficiency performances but implies a review of the classical transmitter architectures. Within this context, some architectures transforming the input signal of the PA and that are candidates for multi-radio applications are considered. In particular, three architectures have been analyzed and compared: the polar architecture with sigma-delta envelope modulator, the polar architecture with pulse width modulator and the cartesian sigma delta architecture. Validation is accomplished with the most critical signals in terms of power dynamics and frequency bandwidth; these are the LTE and mobile WiMAX. At the amplifier output, the band-pass filter plays a key role and many filtering technologies could be envisaged. In particular, we are interested in the BAW technology (Bulk Acoustic Wave) and a filter bank has been synthesized. This research has quantified the key performances of a high efficiency multi-radio transmitter by analyzing the system from baseband signal treatment to RF filtering before the antenna

Texto completoAir traffic evolution around the word result in high air navigation equipments needs. This PhD study focuses on a new digital architecture for UHF (225 MHz – 400 MHz) and VHF (118 MHz -144 MHz) transmitter in aeronautical communications context. New architecture for both current systems and futures systems (which is presently being specified) like LDACS-1 and LDACS-2 systems has to be proposed. The best architecture choice is related to the amplification stage linearization techniques used. This work was carried out in three main steps. First, the best architecture choice suited to our application is made. The second step of the study is dedicated to the architecture digital implementation. Last but no least step is devoted to the experimental validation which allow to assess the system performances

Texto completoModern connected devices need both computing and communication capabilities. For example, smartphones carry a multi-core processor, memory, and several radio transceivers on the same platform. Simpler embedded systems often use a mixed-signal chip that contains both a microcontroller and a transceiver. The physical proximity between digital blocks, which are strong sources of electromagnetic noise, and radio transceivers, which are sensitive to such noise, can cause functional and performance problems. Indeed, there exist many noise coupling paths between components on the same platform or silicon die. In this thesis we explore the security issues that arise from the interaction between digital and radio blocks, and we propose two novel attacks. With Screaming Channels, we demonstrate that radio transmitters on mixed-signal chips might broadcast some information about the digital activity of the device, making side channel attacks possible from a large distance. With Noise-SDR, we show that attackers can shape arbitrary radio signals from the electromagnetic noise triggered by software execution, to interact with radio receivers, possibly on the same platform
Araújo, Moreira Nicolas de. "On heterogeneous networks under non-Gaussian interferences : experimental and theoretical aspects". Thesis, Lille 1, 2019. http://www.theses.fr/2019LIL1I041/document.
Texto completoInternet of Things represents a technical challenge for 5G communications due to is characteristic heterogeneity: the 2.4 GHz ISM band, for example, is shared between different kind of technologies, such Wifi, Bluetooth and Zigbee. In addition to the loss of quality of communication, recent studies show that interference increases significantly the energy consumption. So, dealing with interference becomes an important task to ensure successfull data transmission. The present thesis approaches two aspects of heterogeneous networks. The first part presents an experimental study on the nature of interference between IEEE 802.11 and IEEE 802.15.4 devices, its impacts on the communication reliability and proposes an statistical description of it. The main conclusion of this part is that, on this context, the interference may present a non-Gaussian behavior, more precisely, an impulsive behavior. Recent theoretical works allied with these experimental results show that the α-stable distribution is more adequate to represent impulsive noises. It means that the, once optimal, classical communication architectures based on the Gaussian assumption, particularly the Least Squares based channel estimation and linear receiver, are not optimal anymore present a significant loss of performance. The second part presents a robust MIMO architecutre based on Alamouti coding, supervised channel estimation based on Least Absolute Deviation and p-norm receiver with an estimator for p. The proposed approach outperforms the classical method

Texto completoWith the great developments in wireless communication technologies, Wireless Sensor Networks (WSNs) have gained attention worldwide in the past decade and are now being used in health monitoring, disaster management, defense, telecommunications, etc. Such networks are used in many industrial and consumer applications such as industrial process and environment monitoring, among others. A WSN network is a collection of specialized transducers known as sensor nodes with a communication link distributed randomly in any locations to monitor environmental parameters such as water level, and temperature. Each sensor node is equipped with a transducer, a signal processor, a power unit, and a transceiver. WSNs are now being widely used in the underground mining industry to monitor environmental parameters, including the amount of gas, water, temperature, humidity, oxygen level, dust, etc. The WSN for environment monitoring can be equivalently replaced by a multiple-input multiple-output (MIMO) relay network. Multi-hop relay networks have attracted significant research interest in recent years for their capability in increasing the coverage range. The network communication link from a source to a destination is implemented using the amplify-and-forward (AF) or decode-and-forward (DF) schemes. The AF relay receives information from the previous relay and simply amplifies the received signal and then forwards it to the next relay. On the other hand, the DF relay first decodes the received signal and then forwards it to the next relay in the second stage if it can perfectly decode the incoming signal. For analytical simplicity, in this thesis, we consider the AF relaying scheme and the results of this work can also be developed for the DF relay. The transceiver design for multi-hop MIMO relay is very challenging. This is because at the L-th relay stage, there are 2L possible channels. So, for a large scale network, it is not economical to send the signal through all possible links. Instead, we can find the best path from source-to-destination that gives the highest end-to-end signal-to-noise ratio (SNR). We can minimize the mean square error (MSE) or bit error rate (BER) objective function by sending the signal using the selected path. The set of relay in the path remains active and the rest of the relays are turned off which can save power to enhance network life-time. The best path signal transmission has been carried out in the literature for 2-hop MIMO relay and for multiple relaying it becomes very complex. In the first part of this thesis, we propose an optimal best path finding algorithm at perfect channel state information (CSI). We consider a parallel multi-hop multiple-input multiple-output (MIMO) AF relay system where a linear minimum mean-squared error (MMSE) receiver is used at the destination. We simplify the parallel network into equivalent series multi-hop MIMO relay link using best relaying, where the best relay ...

Texto completoModern communication networks are now confronted with increasing needs in terms of data rates and mobility. The fourth generation developments relies on both new transmission techniques and on improved hardware architectures. The so-called MC-CDMA modulation scheme has recently emerged as one of the most promising technique for future networks physical layer. This modulation scheme combines multi-carrier modulations and spread spectrum technique. The emergence of MIMO techniques provides more data rate or more robustness. The combination of both techniques assumed to be a good compromise in order to meet wide mobility and high data rates constraints. This thesis deals with the study and the implementation of MC-CDMA communication systems and of MC-CDMA combined with MIMO systems. It also considers the definition and the optimization of appropriate design methods on heterogeneous architectures. This work has been done for European MATRICE project and for the Brittany area PALMYRE project. Following a general description of the context and of MC-CDMA, MIMO related principles, a well-proportioned system is presented. Implementation complexity on a mixed DSP-FPGA prototyping board is then analyzed for both systems. MCSE codesign methodology is then considered for MC-CDMA system and MIMO-MC-CDMA system design. The complete design flow is then detailed for both systems. The great interest of these methodologies for such systems optimization is then demonstrated

Texto completoMultiplication of standards and communication protocols allows nowadays a wider range of services for each consumer. If this multiplication of standards is more significant for users, it creates an increased complexity of Rx/Tx communication modules both in RF (3G, 4G), or mmW (W-HDMI, imaging, radar, sensors ) range. These systems Rx/Tx must be able nowadays to support multiple frequency bands (tri-band mobilephone as an example), or agile functions generation, it is called reconfigurable systems. In this context, that this thesis work taking place which aims to address the challenge of high performances tunable capacitances development in RF and mmW range. The first chapter entitled "Emergence of the need for high performances non linear capacitances in silicon technology" identifies the limitations of usual tunable capacitances offer at STMicroelectronics. The second chapter " AttoFarad capacitance characterization: The Challenge of high impedance measurement" discuss the problem of characterization of very small capacity, called attoFarad, used mainly in digital controlled oscillator (DCO). Nowadays these aF capacitance are very difficult to modelize regarding problems of standard measurement methods. We will discuss of a new method for high frequency characteriziation with a relative precision of 50aF 1 to 10GHz. The third chapter entitled "From analog to digital, developments of tunable capacitances up to millimeter frequencies in CMOS and BiCMOS technologies," will focus on figures of merit improvements of the capacitance (tuning ration, resonant frequency, linear law...) through optimization of existing solution (MOS varactor) and the design of new digital architectures. The final chapter "Performances evaluation through referent mmW circuits " exhibit, the design, realization and characterization of two agile functions, a phase shifter and a in-situ tuner, both in the mmW range. To conclude, all these thesis work provide new solutions for the design of RF and mmW circuits. They have extended the tunable capacitances offer at STMicroelectronics in advanced technologie nodes but also to investigate and validate a new concept of characterization necessary for all of these developments

Texto completoIn this work a novel scheme of predistortion of power amplifier nonlinearities is developed and demonstrated. The originality of the proposed system architecture is that the estimation of nonlinearities is carried out at the receiver thanks to a training sequence, and sent back to the transmitter for predistortion. The proposed architecture achieves efficient compensation of power amplifier nonlinearities on WiMAX and LTE standards without extra hardware. An evaluation of consumption savings is carried out, considering digital consumption of the estimation algorithm at the receiver and predistortion Look Up Table refreshment at the transmitter. The results show that the suggested architecture can be applied for high data rate systems at base stations, relay stations and mobile stations as well

Texto completoOver the past few years, consumer wireless communication systems have been implemented using silicon technology (BiCMOS, CMOS). Thanks to the higher operating frequency range of its active components (MOSFET, Heterojunction Bipolar Transistors), silicon technologies have replaced Ill-V technology in wireless communication circuits. Ultra Wideband technologies, used for high power military radars, were recently extended to consumer applications and normalized over the frequency range from 3 to 10 GHz in the United States of America. Within this range, receiver and transmitter architectures are complex. Transposition of a baseband UWB signal at 60 GHz, more precisely the 59-62 GHz band, offers many advantages, such as a simpler system architecture and a reduced die area. SiGe BiCMOS 0.13 µm silicon transistors exhibit a cut-off frequency and a maximum oscillation frequency of 160 GHz. We have designed and measured all the different millimeter circuits of the transceiver such as the oscillator, switch, pulse generator, medium power amplifier, low noise amplifier and detector. The results obtained on these blocks are in agreement with the system specifications we had established. A fully integrated transmitter and a fully integrated receiver circuits were designed and realized. The results demonstrate the capability of silicon technologies for the implementation of new communication systems in the millimeter wave range

Texto completoRadio-Frequency Micro-Electro-Mechanical Systems (RF MEMS) are highly miniaturized devices intended to switch, modulate, filter or tune electrical signals from DC to microwave frequencies. RF Mems switches are characterized by their high isolation, low insertion loss, large bandwith and by their unparalleled signal linearity. Despite these benefits, RF Mems switches are not yet seen in commercial products because of reliability issues, limits in signal power handling and question in packaging. In this context, we put in evidence, a near hermetic packaging based on a micro-machined cap in Foturan sealed onto a photopatternable polymer Benzo-Cyclo-Butene (BCB) as a solution adapted to micro-switches RF. To answer the stakes in conception, we identified needs in multiphysics modelling able to generate behavioural macro-models. Finally, a demonstrator was characterised in terms of return and insertion losses measurements, which assures insignificant impact of the package on the RF losses

Texto completoThe UWB (Ultra Wide Band) consists in transmitting signal between 3. 1 and 10. 6 GHz with a power limited to –41. 3 dBm/MHz. For high data rate (100 to 500 Mbit/s) and short range (1 to 10 m) applications, the state of the art solutions are based on complex digital processing. Mitsubishi ITE proposes an alternative multiband (MB) impulse radio solution based on a non-coherent receiver. The OOK demodulation is done by an original energy detection with a threshold which is adapted dynamically according to propagation conditions. The complete parallelization of this MB-OOK solution allows the system to both avoid inter-symbol interference and recover virtually all available energy. Furthermore the impulsive approach limits multipath channel fading. The comparison of MB-OOK and MB-OFDM systems demonstrates the pertinence of the proposed solution for high data rates and short range applications with low power consumption

Texto completoThe transistors operating frequencies are well above 200GHz in the last silicon technology nodes. These performances have encouraged the research of the communication systems operating at millimeter wave frequencies. Such performances allow higher and higher multi-gigabit data rate and also more compact communication systems with on Silicon integrated antennas.The objective of this research work was to design a multi-gigabit wireless chip to chip communication system at 140GHz. Such a short-range communication system could be designed to improve or replace the inter-chip interconnects where data rates are limited. Secondly this communication system could also be used to improve the testability of on wafer dies by performing contactless test. The communication system with phase noise cancelation topology specifically self-heterodyne and self-homodyne, studied during the research work, are based on the carrier signal emission in addition to the modulated signal simplifies the frequency synthesis of the emitter and receiver parts. Millimeter wave frequency communication systems are conventionally based on carrier frequency recovering system that is complex and consumes a lot of energy. An On-Off Keying (OOK) modulation has been selected and all the parts of the transceiver have been designed in 0.13μm SiGe:C BiCMOS technology. The silicon area of the circuit is 0.31mm² including the antennas. This transceiver achieves a data rate up to 14Gbps at a distance of 0.6mm with an energy efficiency of 5.7pJ/bit. Moreover a self-heterodyne QPSK demonstration at 140GHz was performed with an EVM of 27% to 10Gbps

Texto completoMEMS ("Micro Electro Mechanical Systems") technologies have been successfully introduced in the past decade in order to develop smart micro-systems exhibiting high integration level, new functionalities such as reconfigurability (to switch over different standards) or self repairing ability, and high electrical performances up to millimeterwave frequencies. Moreover, new system architectures can be implemented thanks to these devices, which demonstrate the potentialities of MEMS technologies in future wireless systems. In the meantime, their multi-physic design dealing with electrostatic, mechanical and electromagnetical concerns, translates into a long and complex optimization of the MEMS-based circuits slowing their industrial use. Moreover, few studies are available on the power handling capabilities of these components, which is the key parameter to improve their integration into front-end networks. Our work, made in LAAS-CNRS, concentrates on the design and characterisation of power RF-MEMS switches and their integration into a broadband single pole double throw circuit, for front-end duplexer operating in X band. The first chapter will be dedicated to a multi-physic design methodology for capacitive electrostaticaly actuated RF-MEMS switches design. This methodology, associated with an optimized topology, enables an efficient development of MEMS components and circuits. Demonstrators have been measured and demonstrate outstanding RF performances which validate the proposed methodology. The second part of this work points out the power optimization of RF MEMS switches. A power handling prediction methodology has been proposed and used to optimize the switch described in the first chapter. Simulations have been confirmed by measurements which validate our prediction method. The measured RF MEMS power handling demonstrates the ability of this technology to be used in front-end circuits and systems. Finally, the third chapter deals with an application using the methodologies described above: a broadband (6-18 GHz) power switching circuit for front-end duplexer. This circuit has been optimized, realized and characterized and exhibits state of the art microwave and power performances over a broad frequency band

Texto completoThe advent of increasingly powerful Integrated Circuits (IC) has led to the emergence of the Software Defined Radio (SDR) concept, which brought the sector of secured mobile communications into a new era. The outstanding performance of these systems results from optimal trade-offs among advanced analog/Radio Frequency (RF) circuitry, high-speed reconfigurable digital hardware and sophisticated real-time software. The inherent sophistication of such platforms poses a challenging problem for product testing. Currently deployed industrial test strategies face rising obstacles due to the costlier RF test equipment, longer test time and lack of flexibility. Moreover, an SDR platform is field-upgradeable, which means it will support standards and scenarii not considered during the design phase. Therefore, an in-field test strategy is not anymore 'a nice to have' feature but a mandatory requirement. In this context, our research aims to invent and develop a new test methodology able to guarantee the correct functioning of the SDR platform post-fabrication and over its operational lifetime. The overall aim of our efforts is to reduce post-manufacture test cost of SDR transceivers by leveraging the reconfigurability of the platform.For tactical radio units that must be field-upgradeable without specialized equipment, Built-in Self-Test (BIST) schemes are arguably the only way to ensure continued compliance to specifications. In this study we introduce a novel RF BIST architecture which uses Periodically Nonuniform Sampling (PNS2) of the transmitter (TX) output to evaluate compliance to spectral mask specifications. Our solution supports a stand-alone implementation, is scalable across a wide set of complex specifications and can be easily applied for in-field testing with small added hardware. Compared to existing analog/RF test techniques, this approach is not limited to a given TX architecture and does not rely on an ad-hoc TX model, which makes it ideal for SDR testing

Texto completoSurvey on wireless microsensor networks highlights the main constraint of energy autonomy. In fact, these autonomous and communicating microcomponents named network nodes are scattered into few or not open environment. The goal of our work is to propose a transceiver design method adapted to microsensor networks. After a demonstration of predominant part of RF into the mean power consumption of a microsensor node, we developed three new simulation tools which correspond to different level of transceiver modelling. Their use and obtained simulation results demonstrate the relation between transceiver specifications and performances with power consumption. The association of these tools was used to propose a new design method under power consumption constraint. Finally, we designed, produced and tested a 868 MHz Low Noise Amplifier which presents interesting power consumption characteristics

Texto completoWireless technologies are now widespread due to the easiness of use they provide. Consequently, the number of radio devices increases. Despite of the efforts to reduce radio circuits power consumption as they are more and more numerous, now they must achieve ultra-low power consumption. Today, radio devices are made more efficient to reduce their power consumption especially for the receiving part. Indeed, for asynchronous communication, a lot of energy is wasted by the receiver waiting for a transmission. In order to avoid this waste, new standards have been created such as Zigbee and Bluetooth Low Energy. Due to periodic operation with ultra-low duty cycle, they provide ultra-low power consumption. Another solution to drastically reduce the power consumption has emerged, wake-up receiver. Wake-up receivers are based in simple architecture to provide ultra-low power consumption, they are only in charge to wait for a frame and when it occurs, wake-up the main receiver put in standby mode before that. The proposed wake-up receiver has been designed in NXP CMOS technology 160 μm. It provides a-54 dBm sensitivity, consuming 35 μA which allows a 70m range considering a 10 dBm emitter at 433,92 MHz. This wake-up receiver operates with ASK modulation, compared to others it provides a smart patented calibration system to get the necessary reference voltage for demodulation. This mechanism provide DC offset robustness and does not drain any current while the wake-up receiver is operating. To wake up the main receiver a 24 bits programmable Manchester code is required. This code at 25 kbps is programmable by the use of an SPI interface

Texto completoThe analog-to-digital converter (ADC) is a central component of mixed signal systems as the interface between the analog and digital representation spaces. Its performance bounds that of the device it is integrated in. Indeed, ADC linearity is essential for maintaining in the digital space the reliability of its input signal and then that of the information it carries.Wideband digital radio receivers are particularly sensitive to ADC non-linearities. Single-tone and dual-tone dynamic range (respectively STDR and DTDR) of such systems – i.e. the abilityto process simultaneously signal components with high power ratio – are limited by the spurious free dynamic range (SFDR) and intermodulation distortion (IMD) of their internal ADC.DTDR et de STDR are key metrics for electronic warfare wideband digital radio receivers developed for radiocommunication signal processing. As a matter of fact, these equipments are employed for analyzing the tactical situation of the radiofrequency spectrum in order to support military maneuvers. Hence, signal integrity is critical. This thesis deals with the ADC linearization issue in this context. Thus, it aims to study techniques for increasing ADC SFDRand IMD for the purpose of improving dynamic ranges of electronic warfare wideband digitalr eceivers.In this dissertation, the problematic of ADC linearization is approached in two different ways.On the one hand, we consider distortion compensation using pre-filled look-up tables (LUT). Wepropose an algorithm for filling LUTs that stems from an existing method by halving the numberof coefficients required for the integral non-linearity (INL) estimation. Then, based on this new method, we develop an approach for correcting ADC dynamic non-linearities using a couple ofstatic LUTs and we present an example of algorithm for operating this method. On the other hand,we study linearization solutions that rely on behavioural modelling of ADCs using discrete-time Volterra series and its derivatives. First, we address the three fundamental issues of this approach:modelling ; model identification ; and model inversion. Then, we propose three blind linearization algorithms. Finally, we consider the implementation on field programmable gate array (FPGA) of one of them for the purpose of evaluating the relevance of real-time linearization of an ADC sampling at about 400 MHz
