The book presents the historical evolution of Information Theory, along with the basic concepts linked to information. It discusses the information associated to a certain source and the usual types of source codes, the information transmission, joint information, conditional entropy, mutual information, and channel capacity. The hot topic of multiple access systems, for cooperative and noncooperative channels, is discussed, along with code division multiple access (CDMA), the basic block of most cellular and personal communication systems, and the capacity of a CDMA system. The information theoretical aspects of cryptography, which are important for network security, a topic intrinsically connected to computer networks and the Internet, are also presented. The book includes a review of probability theory, solved problems, illustrations, and graphics to help the reader understand the theory
