Featuring a variety of applications that motivate students, this book serves as a companion or supplement to any of the comprehensive textbooks on communication systems. The book provides a variety of exercises that may be solved on the computer using 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.
