Book Description

Introduction to Adaptive Arrays serves as an introduction to the subject of adaptive sensor systems whose principle purpose is to enhance the detection and reception of certain desired signals. The field of array sensor systems is now a maturing technology. With applications of these systems growing more and more numerous, there is a wealth of widely scattered literature on various aspects of such systems. Unfortunately, few books attempt to provide an integrated treatment of the entire system that gives the reader the perspective to organize the available literature into easily understood parts. Intended for use both as a graduate level textbook and as a reference work for engineers, scientists, and systems analysts, this book provides such an integrated treatment by emphasizing the principles and techniques that are of fundamental importance in modern adaptive array systems.

Book Description

The book addresses the current demand for a scientific approach to advanced wireless technology and its future developments. It gives a clear presentation of both antennas and adaptive signal processing which is what makes antennas powerful, maneuverable and necessary for advanced wireless technology. The book presents electromagnetic signal processing techniques that both control the antenna beam and track the moving station, which is required for effective, fast, dynamic beamforming. The first part of the book presents a comprehensive description and analysis of basic antenna theory, starting from short dipole antennas to array antennas. This section also includes important concepts related to antenna parameters, electromagnetic wave propagation, the Friis equation, the radar equation and wave reflection and transmission through media. The second part of the book focuses on smart antennas, commencing from a look at the traditional approach to beamforming before getting into the details of smart antennas. Complete derivation and description of the techniques for electromagnetic field signal processing techniques for adaptive beamforming are also presented. Artificial Intelligence (AI) driven beamforming is presented using computationally fast and low-memory demanding technique for AI beamforming is presented with the different excitation functions available. A novel method for fast, low memory and accurate, maneuverable single beam generation is presented, as well as other methods for beamforming with fewer elements along with a simple method for tracking the mobile antenna and station. In this section, for completeness, the use of antenna signal processing for synthetic aperture techniques for imaging is also presented, specifically the Inverse Synthetic Aperture Imaging technique. The third part of the book presents technological aspects of advanced wireless technology, including the 5G wireless system and the various devices needed to construct it. While the books’ main emphasis is theoretical understanding and design, it includes applications, and legal matters are also presented.

Book Description

3G, HSPA and FDD versus TDD Networking, Second Edition is the only book that contrasts the network capacity gains that may be achieved with the advent of adaptive antenna arrays and HSDPA-style adaptive modulation techniques in the context of FDD and TDD CDMA cellular networks. In the five years since the first edition of this book was published the wireless landscape has evolved further. The new book addresses the recent developments in the field of HSDPA-style wireless networking, focusing particularly on the issues and challenges of FDD versus TDD networking. These solutions are particularly powerful in shadow-faded scenarios, when the antenna array elements experience correlated, rather than independent fading. Furthermore, the flexible up-link/down-link time-slot allocation of TDD is beneficial for supporting the Wireless Internet, but results in erratic interference fluctuations, which is efficiently combated by the antenna arrays and adaptive modulation. Additionally, whilst the adaptive modulation aided system simply drops the instantaneous transmission rate during instances of high interference, conventional networks would drop the call. Builds on successful previous edition to include recent developments in the field of HSDPA-style wireless networking Provides an all-encompassing self-contained overview of the subject for a wide range of readers of all levels. Treats the topics of both physical-layer and network-layer aspects of wireless systems using a cross-layer optimization approach. One of the first books to contrast in detail both FDD and TDD networking. The material is presented clearly and logically allowing the uninitiated reader to commence reading it at fundamental non-mathematical conceptual level at the beginning of the book, while advanced readers can turn directly to the required chapter describing solutions to a number of wireless FDD or TDD networking problems. This book will inspire researchers, practicing engineers, operators, marketing engineers and advanced postgraduates.
