Publisher's Synopsis
Encyclopaedia of Electronic Communication Systems deals with devices, circuits and systems analysis, and design concepts in a way that keeps students involved and active in the learning process. This Encyclopaedia provides a detailed overview of the communications systems, wireless communications systems with emphasis on the most recent breakthroughs of optical cable technologies based upon Wavelength Division Multiplexing. Various aspects of troubleshooting are discussed throughout. In telecommunication, a communications system is a collection of individual communications networks, transmission systems, relay stations, tributary stations, and data terminal equipment (DTE) usually capable of interconnection and interoperation to form an integrated whole. The components of a communications system serve a common purpose, are technically compatible, use common procedures, respond to controls, and operate in union. The book, Fundamentals of Communication Systems, introduces the basic techniques used in modern communication systems and provides fundamental tools and methodologies used in the analysis and design of these systems. In first chapter, we investigate threshold characteristics of a single mode 1.55 ?m InGaAsP vertical cavity surface emitting laser (VCSEL) with two different optical confinement structures. Second chapter provides an insight into multi-user MIMO systems. We firstly present some of the main aspects of the MIMO communication. We introduce the basic concepts of MIMO communication as well as MIMO channel modeling. In third chapter, we conclude physical layer security for multiuser MIMO communications, especially focusing on the case when multiple malicious users are present in the network, and they can eavesdrop on each other. In fourth chapter, we explore the fundamentals and challenges of indoor VLC systems. Basics of optical transmission such as transmitter, receiver, and links are investigated. Moreover, characteristics of channel models in indoor VLC systems are identified and theoretical details about channel modelling are presented in detail. Fifth chapter gives an approach on exploration of spatial diversity in multi-antenna wireless communication systems. Sixth chapter presents four different integer sequences to construct quasi-cyclic low-density parity-check (QC-LDPC) codes with mathematical theory. The chapter introduces the procedure of the coding principle and coding. Seventh chapter presents a comprehensive study on the evaluation of data communication system (DCS) using dynamic fault tree approach based on fuzzy set. Using a 3D (multilayer) IC structure is proposed in eighth chapter in order to solve most pressing problems appeared in constructing computing systems. Ninth chapter presents about wired/wireless photonic communication systems using optical heterodyning. The main goal of these systems is to reduce infrastructure cost and to overcome the capacity bottleneck in wireless access networks, allowing, at the same time, flexible merging with conventional optical access networks. In last chapter, we discuss the fundamentals of CO-OFDM systems; the WPT based OFDM systems are considered; PMD influence on the CO-OFDM dual-polarization transmission is reviewed; the structure and the properties of CO-OFDM system based on DT-CWT and DT-CWPT are described, respectively.
