The world’s oil and gas is transported using a network of steel pipelines most of which lie underground. The length of this network in the US/Canada alone is 3.5 million kilometers. Keeping track of pipes in such a network for pipeline-health monitoring, maintenance, and logistics is an acute problem faced by pipeline-operators. Recently, radio-frequency-identification tags (RFIDs) have been proposed for tracking pipelines and even for monitoring pipeline health with additional built-in sensors. Low-cost RFID tags are wirelessly powered and battery-less. However, RFIDs do not function optimally in the presence of magnetic carbon steel pipes that are prevalent in the industry. High-frequency wireless signals also attenuate rapidly through wet soils. In this research, the use of passive RFID sensor platforms for interrogating buried pipes up to 1.25 m deep in the LF bands is proposed. Using magnetic-induction-based communication, a test-comparison between conventional full/half duplex (FDX/HDX) and sequential (SEQ) RFID schemes is detailed. Wireless measurements in the presence of an industry-standard ASTM A-53 carbon-steel pipe show a SEQ RFID offering better immunity against magnetic proximity effects of the pipe’s wall with an 8.3 dB (x6.8) improvement over a FDX/HDX RFID operating under similar conditions over a distance of 80–125 cm at which pipes are typically buried.

In asynchronous cognitive networks (CNs), where there is no synchronization between primary users (PUs) and secondary users (SUs), spectrum sensing becomes a challenging task. By combining cooperative spectrum sensing and full-duplex (FD) communications in asynchronous CNs, this paper demonstrates improvements in terms of the average throughput of both PUs and SUs for particular transmission schemes. The average throughputs are derived for SUs and PUs under different FD schemes, levels of residual self-interference, and number of cooperative SUs. In particular, we consider two types of FD schemes, namely, FD transmit-sense-reception (FDr) and FD transmit-sense (FDs). FDr allows SUs to transmit and receive data simultaneously, whereas, in FDs, the SUs continuously sense the channel during the transmission time. This paper shows the respective trade-offs and obtains the optimal scheme based on cooperative FD spectrum sensing. In addition, SUs’ average throughput is analyzed under different primary channel utilization and multichannel sensing schemes. Finally, new FD MAC protocol design is proposed and analyzed for FD cooperative spectrum sensing. We found optimum parameters for our proposed MAC protocol to achieve higher average throughput in certain applications.

Duplekser merupakan perangkat yang dapat mengisolasi receiver dari transmitter saat keduanya saling berbagi antena yang sama, digunakan agar komunikasi bisa berjalan secara full duplex. Ada dua metode transmisi duplex yaitu frequency division duplex (FDD) dan time division duplex (TDD). FDD merupakan teknik duplex yang menggunakan dua frekuensi yang berbeda untuk melakukan komunikasi dalam dua arah, sedangkan TDD menggunakan frekuensi tunggal dan frekuensi tersebut digunakan oleh semua kanal untuk melakukan pengiriman dan penerimaan data. Gabungan dua bandpass filter dengan metoda pseudo-interdigital untuk aplikasi LTE (long term evolution). Metode ini lebih unggul dibandingkan duplekser dengan metoda hybrid. Duplekser bekerja pada FDD LTE band ke-7 yaitu frekuensi uplink 2500-2570 MHz dan downlink 2620-2690 MHz. Dari hasil pengukuran diperoleh sebagai berikut: nilai frekuensi center pada uplink 2639 MHz dan pada downlink 2659 MHz, insertion loss pada uplink 1,561 dB dan downlink 1,74 dB, bandwidth ±70 MHz, isolasi 23,03 dB, serta nilai return loss 23,5 dB pada uplink dan downlink 23,45 dB.

This paper studies sum rate maximization of a cognitive radio network, where a full-duplex relay (FDR) is considered to assist data transmission. An FDR equipped with multiple transmit/receive antennas is introduced to harvest energy from the radio frequency signal of the primary system to reuse the energy for its own data transmission. By exploiting the time-switching relaying protocol, we first formulate an optimization problem for the sum rate of primary and secondary receivers and then propose a low-complexity algorithm to find the optimal solution. Numerical results verify the effectiveness of the proposed technique for wireless information and power transfer in cognitive radio systems.

The present-day communication system uses Frequency Division Duplex (FDD) to emulate the benefits of Full Duplex Communication. But it requires more bandwidth as the cost of the spectrum is very high it becomes a major limitation. To overcome this problem implementation of Full Duplex Communication is the best solution. Implementation of full duplex communication is difficult because of a significant problem called self-interference. while transmitting and receiving signals on the same frequency band, receiving signal is interfered with the transmitted signal this phenomenon is called self-interference. The objective of this project is to minimize that self-interference signal from the received signal by using signal processing technique, LMS echo cancellation. Least Mean Square (LMS) echo canceller whose coefficients are updated iteratively is used to cancel the self-interference. An algorithm based on steepest descent method is used to obtain coefficients that change iteratively with varying step size to solve Weiner-Hopfs equation.

The LTE Long Term Evolution highly developed Technology, Handover is the essential function of the mobility of user in cellular networks in Time Division Duplex as well as Frequency Division Duplex. Handover is one of the essential that can affect the [QoS] Quality of Service with Capacity of Mobile Broadband Networks. Within mobile cellular network communication systems, a (spectrum) limited shared resource needs to be shared with all the users, so full duplex communication is achieved. This paper involves studying diverse Hand over delay parameters and also focus on reducing “Hard Handover delay” by minimizing interruption time, activation time, wireless channel accesses time as well as the wireless link transmission delay. Technique is developed in order to reduce the handover delay time in Time Division Duplex network which too reduces the wireless channel access time and the wireless link transmission delay. A novel handover algorithm is developed which would decreases the handover delay time and access time inside mobile network environment.Additional work may be conceded on to obtain enhanced performance and Quality of service in Time Division Duplex mobile network.

We analyze the ergodic capacity of a dual-hop full duplex amplify-and-forward (AF) vehicle-to-vehicle (V2V) cooperative relaying system over Nakagami-m fading channels. In this context, the impacts of self-interference (SI) at the relay and co-channel interference (CCI) at the destination are taken into account in this analysis. Precisely, based on the analysis of the moment generating function (MGF) of the signal-to-interference-plus-noise ratio (SINR), new exact and lower bound expressions for the ergodic capacity are derived. The ergodic capacity upper bound is also derived based on the asymptotic outage probability of the approximated SINR. Monte-Carlo simulation results are presented to corroborate the derived analytical results. Our results show the significant impact of the considered interferences on the system performance. It is shown that the ergodic capacity is degraded when the average SI at the relay and/or the average CCI at the destination is increased. This highlights the importance of taking these phenomena into account in the performance evaluation in order to assess the practical limit of full duplex relaying (FDR) cooperative wireless communications. Interestingly, it is also observed that FDR with SI and CCI still shows a higher ergodic capacity than the interference-free half duplex relaying, especially at medium to high signal-to-noise ratios (SNRs).

A high-speed full-duplex transceiver (FDT) over lossy on-chip interconnects is presented. The FDT employs a hybrid circuit to separate the inbound and outbound signals from each other and also performs echo-cancellation with the help of the main and the auxiliary drivers. A hybrid MOS device is utilized for impedance matching and conversion of the received voltage signal into a current signal for amplification. Moreover, a compensation capacitance ( C c ) is used at the output of the main driver to minimize the residual echo signal and achieve a higher data rate. The entire FDT architecture has been designed in TSMC 28 nm CMOS standard process with 0.9 V supply voltage. The performance results validate a 16 Gbps FD operation with a root-mean-square (RMS) jitter of 16.4 ps, and a power efficiency of 0.16 pJ/b/mm over a 5 mm on-chip interconnect without significant effect due to process-voltage-temperature (PVT) variations. To the best knowledge of the authors, this work shows the highest achievable full-duplex data rate, among the solutions reported in the literature to date, yet with low complexity, low layout area of 1581 μ m 2 and competitive power efficiency.

The master thesis deals with G.fast and G.mgfast transmission technologies, including their parameters. The work deals with the principle of vector DMT modulation and the possibility of time duplex TDD and full-duplex FDX in two-way communication used in these technologies. The following is a description of the line using the KHM model, which is suitable for simulations in the transmission band using G.fast and G.mgfast technologies. Subsequently, the disturbing effects of crosstalk at the near end of NEXT and the far end of FEXT and their elimination with these technologies are discussing. Part of the work explains supporting calculations to determine the SNR and bit allocation to calculate the baud rate. The work describes the methods of compensation of crosstalk FEXT and NEXT, which affect the resulting baud rate. The work also includes an application for simulation of transmission speed as a function of distance for G.fast and G.mgfast technologies, allowing changing input parameters and adjusting the transmission bandwidth based on G.9700 and G.9701 standards. Also, in work, an application is created to display the compensation of the influence of the transmitted signal crosstalk FEXT and NEXT, which allow the import of measured crosstalk between individual participants. The issue of influencing crosstalk for accurate measurements in the laboratory is also discussing. An application in the MATLAB environment is creating to display the measured characteristics.

Ce travail porte sur la réalisation d’un système FD compact (e.g. applications de type IoT) à partir de composants NF. Pour réaliser un Front-end FD, il est impératif de lutter contre l’auto-interférence (SI) élevée entre émission et réception. Le 1er niveau de réduction de la SI intervient au plus près des antennes (1 TX et 1 RX) pour les miniaturiser puis pour les découpler/isoler l’une de l’autre. Le 2nd a pour fonction de supprimer la SI résiduelle en ajoutant à la réception un signal identique en amplitude à celle de cette interférence mais en opposition de phase. Cet étage requiert un déphaseur variable autour de 180° à environ 1.6GHz et un atténuateur. Comme la topologie retenue pour le déphaseur nécessite des capacités négatives, nos efforts ont d’abord ciblé la réalisation d’un circuit NF basé sur une paire croisée de transistors (XCP) qui constitue le bloc élémentaire de nos dispositifs. Plusieurs idées sont testées pour tendre vers une capacité négative large-bande idéale, mais un circuit stable n’a pu être obtenu qu’en conservant une résistance parasite résiduelle. Ainsi le déphaseur 180° réalisé à base de composants NF voit ses performances être dégradées par rapport au cas idéal. La partie antennaire du front-end FD compact est constituée de 2 antennes planaires très rapprochées. La miniaturisation des antennes est faite en adaptant celles-ci à une fréquence plus basse (1.6 GHz) que leur bande initiale (2.3-2.4 GHz) ou elles sont alors considérées ESA. Une comparaison entre l’adaptation par des réseaux passifs et actifs NF montre que cette dernière permet un élargissement de la bande mais que l’efficacité du système n’est cependant pas améliorée en pratique. Cette limitation provient de la résistance parasite du circuit XCP NF. Le découplage entre antennes à l’aide de circuits NF montre à nouveau un meilleur niveau d’isolation et sur une bande élargie mais sans pénaliser l’efficacité dans ce cas. Au final, les 2 étapes découplage/annulation de la SI sont associés pour obtenir un système FD compact présentant un comportement large-bande de l’adaptation des antennes et de l’isolation (e.g. 45 dB d’isolation à 1,6 GHz). Des perspectives pour réduire la résistance parasite des circuits NF sont proposées pour améliorer l’efficacité du système
This work focuses on achieving a compact FD system (e.g. for wireless IoT) based on NF circuit. The main issue when dealing with FD system is the high self-interference (SI) between transmitter and receiver chains. Thus a two stage decoupling network is studied based on using NF circuits. In this two-level SI canceller, the 1st stage is placed close to the antennas in order to reduce their size, and also to decouple one from each other. The 2nd stage consists of a variable phase shifter and an attenuator. Our goal is to use NF circuit (based on cross-coupled pair of transistors: XCP) to build up a PS tunable around 180° at 1.6 GHz. We identified the origin and solved the stability issue while building a negative capacitance, but a spurious residual resistance remained whatever the improvements made. Our PS performance was thus degraded compared to ideal case.SI cancellation at the antenna level was made by considering two planar monopole antennas (TX and RX). The antennas were miniaturized by making them operate at lower frequency than initially, and then they can be considered as ESA. A comparison between passive matching and NF matching networks showed a wider bandwidth for NF circuits but again the spurious resistor of NF circuit affects the system efficiency. NF circuits also allow improving the decoupling performance (bandwidth and level) compared to passive one but without degrading the efficiency in that case. Finally, we combined the two stages together to get a wideband matching and decoupling response (e.g. 45 dB of SIC at 1.6 GHz for our compact FD system). Some prospects are then put forward in order to face out the residual resistance issue

abstract: Multiple-input multiple-output systems have gained focus in the last decade due to the benefits they provide in enhancing the quality of communications. On the other hand, full-duplex communication has attracted remarkable attention due to its ability to improve the spectral efficiency compared to the existing half-duplex systems. Using full-duplex communications on MIMO co-operative networks can provide us solutions that can completely outperform existing systems with simultaneous transmission and reception at high data rates. This thesis considers a full-duplex MIMO relay which amplifies and forwards the received signals, between a source and a destination that do not a have line of sight. Full-duplex mode raises the problem of self-interference. Though all the links in the system undergo frequency flat fading, the end-to-end effective channel is frequency selective. This is due to the imperfect cancellation of the self-interference at the relay and this residual self-interference acts as intersymbol interference at the destination which is treated by equalization. This also leads to complications in form of recursive equations to determine the input-output relationship of the system. This also leads to complications in the form of recursive equations to determine the input-output relationship of the system. To overcome this, a signal flow graph approach using Mason's gain formula is proposed, where the effective channel is analyzed with keen notice to every loop and path the signal traverses. This gives a clear understanding and awareness about the orders of the polynomials involved in the transfer function, from which desired conclusions can be drawn. But the complexity of Mason's gain formula increases with the number of antennas at relay which can be overcome by the proposed linear algebraic method. Input-output relationship derived using simple concepts of linear algebra can be generalized to any number of antennas and the computation complexity is comparatively very low. For a full-duplex amplify-and-forward MIMO relay system, assuming equalization at the destination, new mechanisms have been implemented at the relay that can compensate the effect of residual self-interference namely equal-gain transmission and antenna selection. Though equal-gain transmission does not perform better than the maximal ratio transmission, a trade-off can be made between performance and implementation complexity. Using the proposed antenna selection strategy, one pair of transmit-receive antennas at the relay is selected based on four selection criteria discussed. Outage probability analysis is performed for all the strategies presented and detailed comparison has been established. Considering minimum mean-squared error decision feedback equalizer at the destination, a bound on the outage probability has been obtained for the antenna selection case and is used for comparisons. A cross-over point is observed while comparing the outage probabilities of equal-gain transmission and antenna selection techniques, as the signal-to-noise ratio increases and from that point antenna selection outperforms equal-gain transmission and this is explained by the fact of reduced residual self-interference in antenna selection method.

Massive MIMO full-duplex relaying (MM-FDR), where multiple source-destination pairs communicate simultaneously with the help of a common full-duplex relay equipped with very large antenna arrays, is studied in this chapter. Different from the traditional MM-FDR protocol, a general model where sources/destinations are allowed to equip with multiple antennas is considered. The effect of hardware impairments is taken into consideration, and is modeled using transmit/receive distortion noises. We propose a low complexity hardware impairments aware transceiver scheme (named as HIA scheme) to mitigate the distortion noises by exploiting the statistical knowledge of channels and antenna arrays at sources and destinations. A joint degree of freedom and power optimization algorithm is presented to further optimize the spectral efficiency of HIA based MM-FDR. The results show that the HIA scheme can mitigate the ``ceiling effect” appears in traditional MM-FDR protocol, if the numbers of antennas at sources and destinations can scale with that at the relay.

This book chapter presents various relay selection policies based on spectral efficient techniques for the next generation mobile systems. Successive opportunistic relaying (SOR) that leverages the half-duplex constraint of conventional relays through concurrent transmissions is described, while proposing techniques to reduce the effect of inter-relay interference (IRI). An extension of SOR is defined for the case of out-of-band relaying, when additional spectrum bands are available and in networks with buffer-aided relays. Moreover, the use of full-duplex (FD) relays is outlined, in view of the effect of loop-interference (LI) from the relay's output to its input and, also, the power reduction is presented. As networks with multiple relays suffer from increased coordination overhead, a reduced Channel State Information (CSI) policy is proposed. For every policy, performance evaluation is provided in terms of outage probability, average throughput, power reduction and switching rate. Finally, open problems in spectral-efficient opportunistic relay selection policies are discussed.

A crescente demanda por largura de banda impulsionou o estudo e o desenvolvimento da quinta geração (5G) de redes móveis. Espera-se que as redes 5G criem mecanismos que permitam uma melhoria no uso do espectro. Antenas full-duplex e técnicas de controle de acesso ao meio (MAC) tendem a ser fundamentais no panorama de redes 5G. Este trabalho propõe uma técnica MAC que reduz a latência da reserva de canal quando se considera o uso de antenas full-duplex. Resultados analíticos indicaram que a técnica proposta obteve ganhos de vazão de até 156% quando comparado com um protocolo do estado da arte projetado para comunicações full-duplex. Quando comparado com esquemas tradicionais half-duplex, o ganho de vazão superou 400%.

A próxima geração (5G) de redes móveis é necessária para satisfazer os crescentes requisitos de vazão em redes cada vez mais densas. As comunicações full-duplex (FD) podem ajudar a cumprir estes requisitos, pois espera-se que elas melhorem a vazão e o uso do canal. Para melhor aproveitar o potencial de FD, as técnicas de controle de acesso ao meio (MAC) devem ser projetadas para tirar vantagem das características de FD. Porém, diversos mecanismos MAC para FD baseiam-se no padrão IEEE 802.11 que fora projetado para comunicações half-duplex. Neste contexto, o presente trabalho propõe o FDMR-MAC (Full-duplex Multiple Receiver MAC). O FDMR-MAC recorre a um mecanismo inovador de reserva de canal para possibilitar melhor uso do canal e maior vazão. O FDMR-MAC é avaliado em comparação com técnicas MAC do estado da arte por meio da extensão de um modelo matemático muito utilizado e baseado em processos estocásticos. Os resultados apontam que o FDMR-MAC supera as demais técnicas avaliadas em todos cenários considerados. A melhoria alcança até 67% em termos de vazão.
