Available in PDF, EPUB and Kindle. Book excerpt: The demand for the higher data rate in the wireless telecommunication is increasing rapidly. Providing higher data rate in cellular telecommunication systems is limited because of the limited physical resources such as telecommunication frequency channels. Besides, interference with the other users and self-interference signal in the receiver are the other challenges in increasing the bandwidth of the wireless telecommunication system. Full duplex wireless communication transmits and receives at the same time and the same frequency which was assumed impossible in the conventional wireless communication systems. Full duplex wireless communication, compared to the conventional wireless communication, doubles the channel efficiency and bandwidth. In addition, full duplex wireless communication system simplifies the reusing of the radio resources in small cells to eliminate the backhaul problem and simplifies the management of the spectrum. Finally, the full duplex telecommunication system reduces the costs of future wireless communication systems. The main challenge in the full duplex wireless is the self-interference signal at the receiver which is very large compared to the receiver noise floor and it degrades the receiver performance significantly. In this dissertation, different techniques for the antenna interface and self-interference cancellation are proposed for the wireless full duplex transceiver. These techniques are designed and implemented on CMOS technology. The measurement results show that the full duplex wireless is possible for the short range and cellular wireless communication systems.

Book excerpt: Due to the tremendous increase in wireless data traffic, one of the major challenges for future wireless systems is the utilization of the available spectrum to achieve better data rates over limited spectrum. Currently, systems operate in what is termed "Half Duplex Mode," where they are either transmitting or receiving, but never both using the same temporal and spectral resources. Full-duplex transmission promises to double the spectral efficiency where bidirectional communications is carried out over the same temporal and spectral resources. The main limitation impacting full-duplex transmission is managing the strong self-interference signal imposed by the transmit antenna on the receive antenna within the same transceiver. Several recent publications have demonstrated that the key challenge in practical full-duplex systems is un-cancelled self-interference power caused by a combination of hardware imperfections, especially Radio Frequency (RF) circuits' impairments. In this thesis, we consider the problem of self-interference cancellation in full-duplex systems. The ultimate goal of this work is to design and build a complete, real-time, full-duplex system that is capable of achieving wireless full-duplex transmission using practical hardware platforms. Since RF circuits' impairments are shown to have significant impact on the self-interference cancellation performance, first, we present a thorough analysis of the effect of RF impairments on the cancellation performance, with the aim of identifying the main performance limiting factors and bottlenecks. Second, the thesis proposes several impairments mitigation techniques to improve the overall self-interference cancellation capability by mitigating most of the transceiver RF impairments. In addition to impairments mitigation, two novel full-duplex transceiver architectures that achieve significant self-interference cancellation performance are proposed. The performance of the proposed techniques is analytically and experimentally investigated in practical wireless environments. Finally, the proposed self-interference cancellation techniques are used to build a complete full-duplex system with a 90\% experimentally proven full-duplex rate improvement compared to half-duplex systems.

Available in PDF, EPUB and Kindle. Book excerpt: With fast increasing demand of the wireless network, the current spectrum used for commercial wireless communication becomes very crowed. So it is critical to find an more efficient way to make the limited spectrum provide larger capacity and throughput. Full-duplex communication technology has caused much attention in the past ten years since it can double the spectrum efficiency theoretically. While the main challenge obstructing it promoting into the market is the self-interference problem in a full duplex system. This dissertation focus on the self-interference cancellation (SIC) theories. The RF impairments occurred in the practical full-duplex system will be discussed. Among them, the phase noise and I/Q imbalance are regarded as the bottleneck of the self-interference cancellation and a detailed analyzing will be included in this dissertation. The general self-interference cancellation methods can be divided into passive self-interference cancellation and active self-interference cancellation where the active cancellation can be further divided into digital cancellation, analog cancellation and hybrid cancellation. This dissertation will review the theories of the passive and active self-interference cancellation. For the analog cancellation, two models (quadratic model and affine model) will be explored to handle the I/Q imbalance and phase noise. Both of these two models are based on the blind tuning algorithm which has two procedures: training and optimizing. This dissertation will introduce the development of the algorithm. It contains the computer simulation results as well as the hardware experimental results to prove the validation of the proposed ideas.

Available in PDF, EPUB and Kindle. Book excerpt: The wireless medium is a shared and limited resource. Current wireless standards always share the medium with Half-Duplex principle: the transmission and reception of signals are done in two separate time slots or two different frequency bands. Besides, the transceiver can only transmit and receive one signal at a time. This dissertation takes an alternate approach: Instead of sharing the medium with Half-Duplex principle, the entire licensed frequency band is shared for simultaneous transmission and reception, which we call Full-Duplex. Besides, the design concept for a wideband flexible radio transceiver can process two different types of signals at a time. To approach this goal, we use an active analog radio frequency self-interference cancellation (AARFSIC) method or a combination scheme of the AARFSIC and active digital self interference cancellation in time domain (ADSICT) to cancel the strong self-interference (SI) induced by the Full-Duplex principle. Based on the Full-Duplex radio, we propose a flexible Full-Duplex Dual-Band (FDDB) OFDM radio transceiver by combining it with a Dual-Band RF front-end. Building on these, we make three main contributions: We present an active self-interference cancellation (ASIC) scheme, which can cancel both the strong one-path and multi-path SI completely, based on the combination of the AARFSIC and DSICT. Next, we introduce the design and evaluation of a Full-Duplex OFDM radio, including the analysis and qualification of the impact of the thermal noise and phase noise on the system performance. Finally, we develop a FDDB OFDM radio that can work on two separate spectrum fragments. In order to eliminate the impact of the I/Q imbalance on the FDDB radio, a simple but practical digital I/Q imbalance estimation and compensation method is presented. The system level simulation conducted with ADS and Matlab software shows that this method can effectively compensate both high and low I/Q imbalance.

This book was released on 2018 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interference in front end transceivers directly impact system performance by saturating receiver circuitry and generating non-linearities. While proper shielding can effectively eliminate external interference, self-interference continues to limit the performance of sensing and communication systems today. Self-interference exists when the transmitted signal interferes with the received signal through parasitic signal paths and from spurious reflections. This dissertation explores the use of novel transducers, front-end designs, and active cancellers to eliminate self-interference in multiple sensing and communication modalities: acoustic, optical, and electronics. First, we demonstrate integration of electroadhesion with a piezoelectric multimaterial fiber transducer to reduce acoustic signal reflection at the interface with the target substrate. The large acoustic impedance of air introduces a 105 mismatch with the acoustic transducer and the substrate. By monolithically integrating electroadhesive and acoustic functions into a single fiber device, the fiber transducer can controllably adhere to the target and subsequently eliminate the interfacial air microvoids during operation. Second, the limited directivity of optical circulators give rise to parasitic signal paths in optical Mach-Zehdner based laser Doppler vibrometers. Parasitic signal paths are signal paths in an interferometer which are unexpected and unbalanced with respect to the signal and reference arms. The path length imbalance demodulates laser phase noise as amplitude noise at the receiver which degrades sensitivity due to the decrease in signal to noise ratio. We derive an expression for this this parasitic phase induced intensity noise (P-PIIN) and develop a new interferometer design which enables mutually balanced signal, reference, and dominant parasitic paths to achieve 90 dB of signal to noise ratio and femtometer vibration sensitivity. Third, self-interference in modern electronic communication systems limit the maximum achievable throughput in a given bandwidth. Self-interference from both parasitic signal paths and spurious reflections overwhelms the significantly weaker receive signal when both are operating simultaneously. As such, communication systems such as cable only operate either in time domain duplexing (alternate between transmitting and receiving) or frequency domain duplexing (transmit and receive on different frequencies) modes. By actively eliminating self-interference, communication systems are able to send and receive information at the same time on the same frequency: full duplex operation.

Available in PDF, EPUB and Kindle. Book excerpt: "Spectrum resources become more and more scarce over last few decades, leading to the significance of effectively utilizing and allocating spectrum. Recently, in-band full-duplex (FD) operation has gained more attention as a potential approach of enhancing spectrum efficiency by simultaneous transmission and reception over the same frequency. One of the most challenging problems in FD communications is the existing strong self-interference (SI) from transmitter and co-located receiver. The SI must be suppressed to a sufficiently low level by a combination of antenna, radio frequency (RF) and baseb and cancellation stages so that the intended signal received from the distant transmitter can be reliably demodulated. In this work, we study the SI-channel characteristics and develop a high performance RF/Analog self-interference canceller (SIC) for a 2x2 MIMO FD transceiver. First of all, SI cancellation technique requires knowledge of SI propagation characteristics and models. We investigate of the wideband SI-channel propagation characteristics of a 2x2 MIMO with dual-polarized antennas. The SI-channels are measured at center frequency of 2.45GHz with 500MHz bandwidth in various environments: anechoic chamber, laboratory room, and corridor. The measurement results show that the SI-channel can be represented by a multipath model composting of two segments: a quasi-static internal SI-sub-channel due to the particular Tx/Rx antenna structure and a time-varying and dynamic external SI-sub-channel due to possible reflections from the surrounding objects. Also, the external SI-channel exhibits cluster arrival features and can be described by a modified Saleh-Valenzuela (S-V) model. In addition, we a develop RF/Analog SIC to suppress the quasi-static internal SI-sub-channel. We discuss SIC design considerations at the system level. Specifically, we consider coupler selection to minimize the noise-figure increase and derive the linearity requirements of RF/Analog SIC, including the component linearity requirements, so that the nonlinear distortion introduced by RF/Analog SIC will not significantly degrade SNR after all the cancellation stages. We propose high-linear RF/Analog SIC with custom-made components. Measurements and simulations with followed digital cancellation stages show that proposed RF/Analog SIC can provide 60-80dB cancellation and negligible SNR degradation (0.3dB) due to nonlinear distortion. Moreover, we specifically focus on the study and design of delay/phase shift module, to meet the RF/Analog SIC linearity requirements. This delay/phase shift module is composed of a RF switched true time Delay line (switched TTD) and an analog variable reflective type phase shifter (RTPS). Measurement results show significant improvement over off-the-shelf products, and other existing prototypes, in terms of linearity." --
