Описание: Design of Digital Phase Shifters for Multipurpose Communication Systems covers a new emerging need in designing digital phase shifters for modern communication systems. With the advancement of new generation mobile communication systems, directed beams save a substantial amount of RF-power, and improve the noise immunity. In this regard, beam-forming circuits, namely, digital phase shifters constitute essential parts of the antenna arrays. Therefore, this book is devoted to design of digital phase shifters for various communications systems. In the good old days, phase shifter design requirements used to demand narrow bandwidth with no physical size constraints. Nowadays, they must be compact and suitable for Very Large Scale Integrated Circuits (VLSI) or Microwave Monolithic Integrated Circuit (MMIC) implementation with Wide Phase Range (WPR) and Wide Frequency Band (WFB). Since the 1980s, the author has been designing digital phase shifters for various applications. He started to work with loaded lines phase shifters, and then employed branch line couplers to achieve wider frequency bands. In order to reduce the physical size, he used a 3 element Symmetric LC ladder based T or PI configurations. In order to achieve broad frequency band with large phase range, usage of LC lattice structures is inevitable. Lately, the author designed phase shifters using both lowpass and highpass LC ladder and lattice based switched-structures, which are suitable for monolithic implementation. In the course of design, MOS transistors were employed as switching elements. This book includes several novel digital phase shifter topologies, which provides wide phase range and wideband operation. Technical topics discussed in the book include:
Basic Concept of Antenna Arrays
Concept of Digital Phase Bit
Scattering Parameters to analyze the electric performance of phase shifters
Transmission Lines as circuit elements to construct practical phase shifters
Loaded Line Digital Phase Shifters (DPS)
Lowpass Based T/PI Section DPS
Highpass Based T/PI Section DPS
3-Element LC T/PI Section DPS
Wide Phase Range, Wide Frequency Band Symmetric Lattice Based DPS
For each topology presented, explicit design equations are provided and programs to assess the electric performance of each topology is developed in a MatLab environment. It is expected that the reader will be self-sufficient to design and implement the digital phase shifters topologies presented in this book.

Описание: This book provides an efficient introduction to fundamental and advanced digital transmission technologies in current and future wireless communication systems. The objective is to help students and engineers quickly grasp the operating principles and design trade-offs of various wireless transmission technologies, which will enable them to carry out product development or perform academic research in the field. With sufficient theoretical depth, the book covers large-scale channel effects; multipath fading; digital transmission over flat fading; fading mitigation through diversity combining; transmission over frequency selective fading; spread spectrum transmission; channel capacity and coding; channel adaptive transmission; MIMO transmission; and advanced topics including multiuser diversity transmission, cooperative relay transmission and multiuser MIMO transmission. The material is presented without assuming an extensive digital communications background from the readers. The design principles of these technologies are manifested with over 100 carefully designed illustrations and over 60 problem-solving examples. The readers can also check their own understanding with extra practice problems at the end of each chapter. Special emphasis is placed on the important trade-off analysis of performance versus complexity.

Описание: The use of the optical spectrum for wireless communications has gained significant interest in recent years. Applications range from low-rate simplex transmission links using existing embedded CMOS cameras in smartphones, referred to as optical camera communications (OCC), mobile light fidelity (LiFi) networking in homes, offices, urban and sub-sea environments to free-space gigabit interconnects in data centers and point-to-point long-range wireless backhaul links outdoors and in space. This exciting book focuses on the use of optical wireless communications (OWC) for mobile use cases. The book discusses existing conventional radio frequency (RF)-based wireless access technology and presents the challenges that can impact the requirements of the future wave of new wireless services in the context of artificial intelligence (AI) driven autonomous systems and machine-type communications. The relationship between visible light communications (VLC) and light fidelity (LiFi), is explored, and the major advantages of VLC and LiFi such as security and data density, and discuss existing research challenges are also introduced. Channel modeling techniques are provided for mobile multiuser scenarios, and will introduce key building blocks to achieve LiFi cellular networks achieving orders of magnitude improvements of area spectral efficiency compared to state-of-the-art. Challenges that arise from moving from a static point-to-point visible light link to a LiFi network that is capable of serving hundreds of mobile and fixed nodes are discussed. An overview of recent standardization activities and the commercialization challenges of this disruptive technology is also provided.
