Book Description
To support the increasing demand of various high data-rate wireless communications, the 7 GHz band at 57-64 GHz has been allocated by the FCC for unlicensed system applications. This decision results in the formations of several standards aiming to develop multi-gigabit wireless communication systems, e.g., IEEE 802.15.3c, IEEE 802.11ad, and WiGig, among many others. One of their common and ultimate goals is to expedite the realization of widespread integrated circuits supporting large data transfers over the air. Designing a digital baseband receiver for the 60 GHz communication system (802.15.3c/802.11ad) requires the following features: (1) a proper architecture to mitigate design challenges of the high-speed analog-to-digital converters (ADCs) that are required by the synchronizer of the receiver; and (2) an effective technique to decouple the interferences that result from adjacent channel estimation sequences (CESs) as well as degrade the equalizer performance of the receiver. To fulfill these requirements, this work realizes the following: (1) a fractional-sampling-rate (FSR) digital baseband receiver to relax the ADC sampling rate requirement through multi-rate signal processing techniques; and (2) a high-accuracy channel estimator to reconstruct interference-less CES responses for improving the BER performance of the equalizer. Compared with the prior arts, the 65 nm CMOS implementations of (1) and (2) demonstrate the feasibilities of reducing the required ADC sampling rate by 25%, and assisting the equalizer in achieving 170x BER reduction, respectively.

Book Description
Orthogonal frequency-division multiplexing (OFDM) access schemes are becoming more prevalent among cellular and wireless broadband systems, accelerating the need for smaller, more energy efficient receiver solutions. Up to now the majority of OFDM texts have dealt with signal processing aspects. To address the current gap in OFDM integrated circuit (IC) instruction, Chiueh and Tsai have produced this timely text on baseband design. OFDM Baseband Receiver Design for Wireless Communications covers the gamut of OFDM technology, from theories and algorithms to architectures and circuits. Chiueh and Tsai give a concise yet comprehensive look at digital communications fundamentals before explaining modulation and signal processing algorithms in OFDM receivers. Moreover, the authors give detailed treatment of hardware issues -- from design methodology to physical IC implementation. Closes the gap between OFDM theory and implementation Enables the reader to transfer communication receiver concepts into hardware design wireless receivers with acceptable implementation loss achieve low-power designs Contains numerous figures to illustrate techniques Features concrete design examples of MC-CDMA systems and cognitive radio applications Presents theoretical discussions that focus on concepts rather than mathematical derivation Provides a much-needed single source of material from numerous papers Based on course materials for a class in digital communication IC design, this book is ideal for advanced undergraduate or post-graduate students from either VLSI design or signal processing backgrounds. New and experienced engineers in industry working on algorithms or hardware for wireless communications devices will also find this book to be a key reference.

Book Description
Future wireless systems will range from sub-6 GHz to above 60 GHz so that large bandwidths could be exploited to support higher wireless traffic for different services. Link configuration and baseband signal processing are the two of the most important factors that determine the quality of wireless communications. They must be carefully designed such that those spectra could be efficiently used. In particular, the hardware impairments in practical implementation and the wireless channel dynamics due to mobility are two challenging issues that should be considered in the system designs. This dissertation has two parts. The first part addresses the challenges in millimeter wave (mmWave) link configuration design, which includes non-coherent beam alignment and reinforcement learning (RL)-based codebook selection, user scheduling, and relay selection. The second part focuses on leveraging deep learning (DL) techniques to enhance the baseband signal processing of orthogonal frequency-division multiplexing (OFDM) receivers. In the first part of this dissertation, we focus on designing mmWave link configuration protocols which take hardware impairments and wireless channel dynamics into account. To have a better insight into the practical implementation and perform a realistic evaluation of our designs, we develop a low-cost mmWave testbed using SiBEAM 60 GHz phased arrays and Universal software radio peripherals (USRPs). In the first contribution of this part, we develop a compressive phase retrieval (CPR) algorithm to estimate the mmWave channel only with the magnitude of training measurements. In particular, we also incorporate side information in the form of prior knowledge of the angle information of the dominant path, to reduce the beam training overhead. In the second contribution of this part, we develop a novel Thompson sampling (TS)-based online learning algorithm to solve the mmWave codebook selection problem under fast varying channels. In particular, we derive the theoretical regret upper bound of the proposed TS-based algorithm. We validate the superiority of the above two types of algorithms, in comparison with the state-of-the-art benchmarks, with the real-world measurements collected by our mmWave testbed. In the third contribution of this part, we further study the mmWave link configuration from a network-layer perspective by jointly designing user scheduling and link configuration with mobility. In particular, we develop two reinforcement learning (RL)-based online solutions to dynamical perform the task. In the second part of this dissertation, we study the potential gain of applying deep neural network (DNN) to perform the post-synchronization baseband signal processing. We develop a DL-based OFDM receiver that is compliant with the latest Wi-Fi standard IEEE 802.11ax. For training its DNN, we first generate a comprehensive synthetic dataset that covers typical wireless local area network (WLAN) indoor channel models and radio frequency (RF) impairments. Then, we develop a passive sniffing-based data collection testbed to capture a large number of real-world OFDM symbols. The value of our proposed DL-based OFDM receiver is comprehensively validated by both synthetic and real-world datasets in comparison with a conventional Wi-Fi receiver
