Available in PDF, EPUB and Kindle. Book excerpt: The explosion of personal devices that need ubiquitous connectivity is making both wireless and wireline communication experience increasingly rapid growth in data-rates. Wireless channels have been `fortunate' to see new channels/standards being made available over the past decade to meet up to multi-Gb/s demands. One such medium is the wideband 60GHz channel. Wireless mediums, by definition however, are thwarted by multi-path reflection-based inter-symbol interference (ISI) -- a problem which becomes only worse at higher speeds. For decades, equalizers have been used efficiently to mitigate such interference. However, wireless equalizers in commercial CMOS products are typically implemented in DSP along multi-level modulation schemes like OFDM, which when scaled to Gb/s speeds dissipate substantial power. This is particularly detrimental for handheld/mobile devices with limited battery capacity. To ease the power bottleneck for equalization, this work instead proposes using mixed-signal techniques. As opposed to classic multi-level ADC/DSP design, such techniques are inspired by high-speed chip-to-chip wired communication that advocates the use of simple modulation schemes (such as QPSK) with few comparators. Since wireless channels suffer ISI with longer delay spreads than their wired counterparts, previously developed wireline equalizers cannot be directly ported. This work therefore enables energy-efficient equalizers to cancel extremely long ISI delay spreads. Our first prototype demonstrated a 40-coefficient complex (I/Q) decision feedback equalizer (DFE) in 65nm CMOS to enable 10Gb/s rates over line-of-sight (LOS) 60GHz channels, while consuming only 14mW of power. The second prototype in 65nm low-power (LP) CMOS enables non-line-of-sight (NLOS) channel equalization as well, by using a 32-coefficient receiver feedforward equalizer (FFE) and a longer 100-coefficient DFE, achieving 3.5-8Gb/s rates while consuming 20-67mW. While the equalizer prototypes in this dissertation have been targeted towards 60GHz channels, the techniques enable energy-efficient equalization for long ISI delay spreads for any high-speed wireless or wireline communication link.

This book was released on 2019-12-03 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid proliferation of the Internet has been driving communication networks closer and closer to their limits, while available bandwidth is disappearing due to an ever-increasing network load. Over the past decade, optical fiber communication technology has increased per fiber data rate from 10 Tb/s to exceeding 10 Pb/s. The major explosion came after the maturity of coherent detection and advanced digital signal processing (DSP). DSP has played a critical role in accommodating channel impairments mitigation, enabling advanced modulation formats for spectral efficiency transmission and realizing flexible bandwidth. This book aims to explore novel, advanced DSP techniques to enable multi-Tb/s/channel optical transmission to address pressing bandwidth and power-efficiency demands. It provides state-of-the-art advances and future perspectives of DSP as well.

This book was released on 2024-07-24 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neural network control has been a research hotspot in academic fields due to the strong ability of computation. One of its wildly applied fields is robotics. In recent years, plenty of researchers have devised different types of dynamic neural network (DNN) to address complex control issues in robotics fields in reality. Redundant manipulators are no doubt indispensable devices in industrial production. There are various works on the redundancy resolution of redundant manipulators in performing a given task with the manipulator model information known. However, it becomes knotty for researchers to precisely control redundant manipulators with unknown model to complete a cyclic-motion generation CMG task, to some extent. It is worthwhile to investigate the data-driven scheme and the corresponding novel dynamic neural network (DNN), which exploits learning and control simultaneously. Therefore, it is of great significance to further research the special control features and solve challenging issues to improve control performance from several perspectives, such as accuracy, robustness, and solving speed.

Available in PDF, EPUB and Kindle. Book excerpt: Explaining what CWDM is, how it is achieved, and why it should be deployed, Coarse Wavelength Division Multiplexing: Technologies and Applications merges coverage of isolated aspects of Coarse Wavelength Division Multiplexing (CWDM) traditionally found as device-related or specific system topics. Emphasizing cost savings and performance enhancement, the book integrates information on component issues, system architectures, concepts for extensions and upgrades, as well as practical applications into a comprehensive, single-volume resource. Beginning with a summary of the ITU-T standards defining CWDM, the book addresses the three essential component classes, optical fibers, transceivers, and WDM filters, which combine to form the basis for the CWDM transmission link. The following chapters include coverage of different architectures such as hubbed rings and meshed networks, and upgrade paths to overcome limitations of current CWDM systems. The book outlines the feasibility of optically amplified CWDM systems, investigates the challenges present with high-speed CWDM and bidirectional transmission, and finally elucidates the importance of CWDM for a wide range of applications. Each chapter provides sufficient information to be used independently and contains references to relevant papers and articles for further study. The last sections of the book focus on applications and case studies where CWDM plays an ever-increasing role. They include extensive studies on networking, reach extension by amplification, and the latest concepts of transmission capacity upgrades using increased bit-rates or new channel plans. Filled with practical information, the book provides a clear understanding of recent developments in the dynamic field of CWDM.
