Communication Systems Principles Using MATLAB

Introduction

Telecommunications encompasses a vast range of subdisciplines, and any treatment must strike a balance between the breadth of treatment and depth in specific areas. This book aims to give an overview with sufficient technical detail to enable coverage from the physical layer (how the electrical or wireless or optical signal is encoded) through to the representation of real‐world information (images, sounds) and then to the movement of that data from one point to another and finally how to encode information and ensure its secure transmission.

Apart from the first chapter, most chapters may be studied as stand‐alone entities or chosen for specific courses. Each chapter includes a Useful Preliminaries section at the start, which reviews some important concepts that may have been studied previously, and places them in the context of telecommunications.

Chapter 1, “Signals and Systems,” introduces and reviews some basic ideas about signals that convey information. The emphasis is on operations that can be performed on signals, which are important to create telecommunication subsystems such as modulators. The idea of block diagrams, and synthesizing complex systems from simpler functional blocks, is also introduced.

Chapter 2, “Wired, Wireless, and Optical Systems,” covers the means of physical transmission of telecommunication signals – either through wired systems such as copper or coaxial cable, wireless or radio systems, or fiber optics. Each is treated separately, ...
