Summary

Featuring a variety of applications that motivate readers, this book serves as a companion to any of the comprehensive books in communication systems. This book provides a variety of exercises that may be solved on the computer using MATLAB? (The authors assume that the student is familiar with the fundamentals of MATLAB). By design, the treatment of the various topics is brief. The authors provide the motivation and a short introduction to each topic, establish the necessary notation, and then illustrate the basic concepts by means of an example.
