Communication systemsThis bestselling, easy to read, communication systems book has been extensively revised to include an exhaustive treatment of digital communications. Throughout, it emphasizes the statistical underpinnings of communication theory in a complete and detailed manner. New features include MATLAB computer experiments that demonstrate important aspects of communication theory; Expanded coverage of emerging digital technologies, such as digital subscriber lines (DSL), carrierless amplitude modulation/phase modulation (CAP), and discrete multitone (DMT); Dozens of examples that relate theory to realworld communication systems. Superbly organized, the text skillfully guides students through topics ranging from pulse modulation to passband digital transmission, and from random processes to errorcontrol coding. Throughout, Haykin presents difficult concepts in language that students can easily understand.
