Abstract:
In this paper, a novel Artificial Neural-Network (ANN) based multi-sensor multi-band adaptive signal-processing scheme is described for enhancing acoustic-speech corrupted by real noise and reverberation. Numerically robust adaptation-algorithms are employed for the ANN based sub-band filters; and, new simulation experiments are reported using real-reverberant automobile data which demonstrate that the proposed speech-enhancement system is capable of outperforming conventional linear filtering-based wide-band and multi-band noise-cancellation schemes.

Abstract:
In this paper, an ultra-wide band (UWB) low noise amplifier (LNA) is implemented by using 90nm RF CMOS technology. The designed LNA achieves high flat band gain (S21) and low noise figure (NF) in the frequency of interest. The proposed LNA operates in the frequency range of 3GHz to 8GHz. In this work, wide band matching is achieved by designing common gate configuration at the input stage. The current reuse and noise cancellation techniques are introduced to improve flat band gain and minimize both noise figure and power consumption. The noise figure is improved by cancelling dominant noise sources with additional hardware. The proposed LNA attains flat band gain of 26.5dB and input matching less than -12dB for entire UWB band. This work achieves noise figure of 2.1dB to 2.59dB in frequency band of interest. Additionally, power consumption of the circuit is 20mW at 1.8V supply voltage.

Abstract:
Abstract In-band full-duplex (IBFD) technology can potentially improve spectrum efficiency compared to half-duplex technology. The cancellation of the self-interference (SI) signal is the key to implementing the IBFD system to achieve accurate detection of the signal of interest. In this work, we fully account for the effect of IQ imbalance, phase noise (PN), additional Gaussian white noise (AWGN), and the nonlinear caused by the RF impairments of power amplifier, and adopt the method of canceling SI signal combined with the propagation, analog, and digital domain to cancel the SI signal, but the residual SI signal is still mixed with the signal of interest in the same time and frequency domain. In addition, a novel multi-domain blind source separation (MDBSS) self-interference cancellation method implemented by using the off-the-shelf components is proposed in this paper, which can realize the separation of residual self-interference signals from the signal of interest (SOI). Additionally, the multi-domain blind source separation (MDBSS) self-interference cancellation technique is used to achieve 75 dB of self-interference cancellation performance, which is proven through numerical simulation analysis, and the SOI is successfully separated in the receiver. Moreover, the multi-domain blind source separation (MDBSS) method in this paper can be applied to radar, jammer, and communication systems in the future.

Abstract:
AbstractFor a frequency‐division duplex (FDD) wide‐band code‐division multiple‐access (WCDMA) system, transmit (TX) signal leakage at the receiver input degrades the receiver performance. To cancel this TX leakage, a frequency selective feedback was previously proposed, but it had an unpredictable feedback loop characteristic due to the uncertainty of the duplexer impedance. This paper presents a new method to achieve TX leakage cancellation regardless of the duplexer impedance. In addition, a local oscillator (LO) phase shift technique is proposed to apply this method for multi‐band. A receiver adopting these proposed techniques is implemented using a 0.18‐μm CMOS process to prove the concept. The measured TX attenuations of the high‐ and low‐band are 17‐dB and 20‐dB, respectively, and the measured noise Figure (NF) degradations of the high‐ and low‐band are 0.6‐dB and 0.5‐dB, respectively. The measurement results demonstrate effectiveness of the proposed techniques.

Abstract:
This paper employs a self-interference cancellation (IBFD-UWA) system for shallow-water acoustic channels by depending on the model of communication channel for SI cancellation, which is based on geometry to accommodate any possible changes in the underwater environment. UWA channels have propagation characteristics based on the configurations of straight and multi-direction mirrors between a transmitter and a receiver. This propagation at the node itself and between the two nodes to transfer information between the nodes operating in the IBFD mode, orthogonal frequency division multiplex (OFDM) modulation with quadrature phase-shift keying (QPSK) mapping. By using numerical simulations, it can be shown that the developed model is able to accurately describe the underwater acoustic environment. The results indicate that local multipath propagation delays can exceed 1.4s with transmission losses of up to 80dB, and the SIC requires about 4 seconds to reduce SI signals to background noise levels successfully.

Abstract:
A broadband (0.8–5[Formula: see text]GHz) CMOS current-mode direct-conversion receiver has been integrated in a 0.18-[Formula: see text]m CMOS process. The proposed receiver front-end features a broadband active-balun low-noise transconductance amplifier (LNTA) driving a current-mode passive mixer terminated by a low-input-impedance transimpedance amplifier (TIA). The receiver chain has improved robustness to out-of-band interference, conversion gain and outstanding linearity. With the technique of noise and distortion cancellation which performs a better input impedance matching, we employ a broadband common-gate–common-source (CG–CS) LNTA and a current mirror to improve both gain and noise figure (NF) performance. Compared to the 50% duty-cycle switching stage, the 25% duty-cycle I–Q switching stage is implemented by using serial switches driven by 50% quadrature local oscillator (LO) signals separately, which improves the down-conversion gain by 3[Formula: see text]dB and lowers the noise figure. The transimpedance amplifier employs the [Formula: see text]-boosting technique to realize low input impedance and high transimpedance gain. The core circuit (RF and baseband signal path) consumes 26[Formula: see text]mW, and the prototype receiver achieves approximately 33–34.5-dB conversion gain, 8.1–9.35-dB NF and 7.5–9.8-dBm IIP3 from 0.8[Formula: see text]GHz to 5[Formula: see text]GHz.

Abstract:
To meet the demand for high-precision positioning in commercial industrial internet scenarios, 3GPP introduced the Positioning Reference Signal (PRS) in the 5G standard. However, the PRS signal occupies specific time and frequency resources for transmission in 5G systems, limiting the efficiency of communication signal transmission to some extent. In this regard, we propose a 5G NR Co-Band PRS model that allows for the superimposition of PRS signals on communication signals in a low-power manner, without requiring additional communication resources or causing too much interference to the communication signal. Since orthogonal frequency division multiplexing (OFDM) signals are sensitive to synchronization errors, we have developed a three-stage Co-Band PRS-based reception scheme. First, an innovative weighted window coarse synchronization method is proposed to enhance the performance of capturing communication signals at a low signal-to-noise ratio (SNR). Next, the interference cancellation technique is utilized to remove the communication signals, and the synchronization error is corrected through multipath delay estimation. Finally, to further improve the ranging accuracy, we propose an iterative delay-locked loop (DLL) algorithm that can achieve a tracking accuracy of one percent sampling. Simulation and real environment tests confirm that the proposed Co-Band PRS reception scheme can achieve a ranging accuracy of 0.16 m@90%.

Abstract:
De nos jours, la consommation d’énergie devient un des principaux défis à surmonter dans le développement des réseaux de communications mobiles. L’amplificateur de puissance est le composant le plus gourmand en énergie dans les stations de base. La cinquième génération de téléphonie mobile de part ses larges bandes de communication et ses modulations complexes augmente encore plus les contraintes sur l’amplificateur de puissance. Pour palier ce problème, il est courant de faire appel à des techniques de pré-distorsion. Une contrainte importante dans la mise en oeuvre de cette technique est la numérisation de la sortie de l’amplificateur qui, dû aux non-linéarités, s’étale sur un spectre significativement plus large que le signal utile, environ 5 fois en pratique voire plus. Habituellement, pour cette opération de numérisation, un Convertisseur Analogique Numérique (CAN) du type pipeline est utilisé car il permet d’obtenir des résolutions supérieures à 10 bits sur une bande de plusieurs dizaines voire centaines de MHz. Cependant, sa consommation d’énergie élevée pousse à explorer d’autres pistes. L’architecture "Multi Stage Noise Band Cancellation" (MSNBC) à base de modulateurs Delta Sigma a l’avantage de réaliser des dynamiques différentes par sous bande et est ainsi un candidat de choix pour le CAN de la boucle de retour des techniques de pré-distortion. L’objectif de ce travail est de démontrer la faisabilité de l’architecture MSNBC qui jusqu’à présent a été uniquement étudiée au niveau système. Ces études nous ont permis de proposer une architecture adaptée pour la numérisation d’un signal de bande RF 20 MHz avec des résolutions différentes par sous bande. Une architecture Zéro-IF tempscontinu avec un modulateur primaire du second ordre et un modulateur secondaire du quatrième ordre avec des quantificateurs 4 bits a été adoptée. Cette architecture a été implémentée en une technologie CMOS 65 nm. Les simulations électriques du MSNBC 2-4 avec un signal LTE ont permis d’obtenir 84.5 dB de SNDR dans la bande principale et 29.2 dB dans la bande adjacente contenant les produits d’intermodulation
Power consumption is nowadays one of the main challenges to overcome in the development of mobile communications networks. The power amplifier (PA) is the most power hungry component in base transceiver stations. The upcoming fifth generation of mobile telephony with wider communication bands and complex modulations further increases the constraints on the PA. To overcome this problem, it is common to use predistortion techniques that enable the power amplifier to operate with greater linearity and efficiency. An important constraint in the implementation of this technique is the digitization of the output of the amplifier which, due to non-linearities, spreads over a significantly wider spectrum than the initial signal, about 5 times in practice or even more. Pipeline Analog-to-Digital Converters (ADCs) are commonly used for this operation because it allows resolutions of greater than 10 bits to be obtained over a band of several tens or even hundreds of MHz. However, its high energy consumption pushes to find a better solution. The "Multi Stage Noise Band Cancellation" (MSNBC) architecture based on Delta Sigma modulators has the advantage of realizing different dynamics per subband and is thus a prime candidate for the feedback loop ADC of predistortion techniques. The purpose of this work is to demonstrate the feasibility of the MSNBC architecture that has so far only been studied at the system level. Our investigations allowed us to propose a suitable architecture to digitize a 20 MHz RF band signal with different resolutions per subband. A continuous time Zero-IF architecture with a second-order primary modulator and a fourth-order secondary modulator with 4-bit quantizers was adopted. This architecture has been implemented in a 65 nm CMOS technology. Transistor level simulations of the 2-4 MSNBC architecture simulations with an LTE test signal resulted in 84.5 dB SNDR in the main band and 29.2 dB in the adjacent band which contains the intermodulation products

Abstract:
"The transmission system is subjected to multi-harmonic torque excitation of the engine, random excitation of road, dynamic meshing excitation of gears, and contact excitation of bearings, etc. Wide-band strong excitation acts on a multi degree of freedom nonlinear vibration system, and the transmission route and vibration phenomenon are complicated, vibration and noise issues are prominent. At the same time, the bending torsional coupled vibration, the box and shafts system coupled vibration, and the various modes coupled vibration of the transmission system will also generate strong dynamic loads, and even cause fatigue damage to parts and power interruptions in severe cases. Therefore, it is necessary to further study the vibration characteristics of the multi-stage planetary transmission system, especially the coupling mechanism of the vibration. Most previous researches are based on linear vibration theory or low degree of freedom systems, and less consideration is given to such multi degree of freedom nonlinear transmission systems with strong coupling. However, in multi degree of freedom nonlinear systems, the resonance phenomenon is complex and unavoidable, and under the action of multi-source wide-band strong excitation, multiple resonance phenomena such as main resonance and combined resonance may be induced, which is more complicated than simple systems. Therefore, it is also necessary to deeply study the coupling vibration mechanism of the system and suppress the system resonance. Based on the nonlinear factors such as tooth profile error, dynamic clearance, time-varying meshing stiffness and damping, manufacturing error, installation error, mass eccentricity and geometric eccentricity, a multi degree of freedom nonlinear transverse-torsional-pendulum coupled vibration model of single-stage planetary gear system is established. Under different working conditions, the vibration amplitude and phase of each component were studied, and the vibration form between each component was analyzed. Through frequency domain and time-frequency analysis of vibration response, the vibration coupling relationship between each direction and each component of the system under different working conditions is studied. Through the sensitivity analysis of the system parameters inertia, mass, stiffness of the supporting shaft and mesh stiffness, the key parameters which have great influence on the coupling vibration of the system are identified. The system coupling degree analysis standard of coupling vibration is established, and the influence rule of sensitive parameter change on coupling vibration is summarized. On the basis of coupling vibration analysis, this paper summarizes the coupling vibration analysis method of the system, and optimizes the system to achieve the purpose of vibration suppression."

Abstract:
This paper presents research focusing on developing and simulating a new way of digital demodulation for the front end Radio frequency (RF) mechanically using MEMS electrostatic actuator by sensing the displacement of a parallel-plates. The operating principle based on the coupling multi-physics of the proposed demodulation device is explained. The analytical modeling and simulation results with experimental data are presented. Recent developments in the Micro Electro Mechanical Systems (MEMS) technology have shown the benefits of reliable mechanical strength that merges with electrical properties. Interest has increased and thus on to improve their performance by applying MEMS technology as to replace existing industrial parts and tools. A typical RF receiver consists of a front end, a band-pass filter, low noise amplifier (LNA), a local oscillator, and a mixer that recovers a baseband signal from a modulated RF signal. In a heterodyne receiver there is more than one intermediate stage. ASK and FSK digital demodulation using electrostatic actuator indicates better feasibility at lower frequency lower than 100 Hz for digital demodulation while indicating wide range of potential baseband range up to 1 kHz.
