"The recent strong interest in wireless technology has put this classic in even more demand than when it was first published. Many engineers are rediscovering territory originally covered in Communication Systems and Techniques. Engineers and engineering students with an interest in mobile communications, wireless technology, and statistical communication theory will find this book to be an excellent reference It is a testimony to the foresight and skill of its authors."
Thomas G. Robertazzi, State University of New York at Stony Brook

This seminal presentation of the applications of communication theory to signal and receiver design brings you valuable insights into the fundamental concepts underlying today s communications systems, especially wireless communications. Heretofore unmatched in its treatment of the subject, Communication Systems and Techniques covers topics such as:

• Basic notions on design for fading radio channels
• Fundamentals of modulation theory
• Methods for probabilities calculations of error rates
• Outage probabilities

Carefully organized and free of academic jargon, this industry classic is a must–have for radio systems developers (satellites, wireless cellular, microwave relay), engineers involved in interpreting propagation influences, and advanced–level students.
