Chapter 14. Modeling and Simulation of Waveform Channels

Introduction

Modern communication systems operate over a broad range of communication channels including twisted pairs of wires, coaxial cable, optical fibers, and wireless channels. All practical channels introduce some distortion, noise, and interference. Appropriate modulation, coding, and other signal-processing functions such as equalization, are used to mitigate the degradation induced by the channel and to produce a system that satisfies the throughput and quality of service objectives while meeting the constraints on power, bandwidth, complexity, and cost. If the channel is relatively benign (e.g., does not significantly degrade the signal), or is well characterized, the design of ...
