Authors’ Note on Title: Having seen Dread Zeppelin live in 1999, we realize weneed make no apologies to Led Zeppelin for abusing their song’s title. Further-more, we selected our working title before the industry went and did it. Oureditor wanted a subtitle mentioning the book’s actual content.

The fundamental principles of telecommunications have remained much the samesince Shannon’s time. What has changed, and is continuing to change, is how thoseprinciples are deployed in technology. One of the major ongoing changes is theshift from hardware to software. Telecommunication Breakdown: Concepts ofCommunication Transmitted via Software-Defined Radio reflects this trend byfocusing on the design of a digital software-defined radio.

Telecommunication Breakdown: Concepts of Communication Transmitted viaSoftware-Defined Radio helps the reader build a complete digital radio that includeseach part of a typical digital communication system. Chapter by chapter, the readercreates a MATLAB® realization of the various pieces of the system, exploring the keyideas along the way. In the final chapter, the reader “puts it all together” by buildinga complete receiver. This is accomplished using only knowledge of calculus, Fouriertransforms, and MATLAB.

Key benefits: • a hands-on approach that provides the reader with a sense of continuity and

motivation for exploring communication system concepts• provides invaluable preparation for industry, where software-defined digital radio

is increasingly important• CD-ROM extras include lesson PDFs; final projects; “received signals” for

assignments and projects; all MATLAB code presented in the text; a bonuschapter on QAM Radio

“The wireless telegraph is not difficult to understand. The ordinarytelegraph is like a very long cat. You pull the tail in New York and itmeows in Los Angeles. The wireless is the same, only without the cat.”
