Extensively revised and updated, this new fourth edition of COMMUNICATION SYSTEMS is the most complete undergraduate textbook on the theories and principles behind today's most advanced communications systems.

New features include:

• MATLAB computer experiments that demonstrate important aspects of communication theory
• Expanded coverage of emerging digital technologies, such as digital subscriber line (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.
