This best-selling, 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 multi-tone (DMT); Dozens of examples that relate theory to real-world communication systems. Superbly organized, the text skillfully guides students through topics ranging from pulse modulation to passband digital transmission, and from random processes to error-control coding. Throughout, Haykin presents difficult concepts in language that students can easily understand.
