Modern Modem Design

 February 26-28


Modems perform the modulation and demodulation tasks required to process waveform signals that are transmitted through and are received from analog channels. The task they perform is conceptually simple; communicate at a distance.  The implementation has evolved over many years from simple broad-band radiators and detectors to very sophisticated signal processing engines. We are so connected by radio, wire, and fiber channels we are hardly able to be impressed by the technology in which we are immersed. This course emphasizes the physical layer of a modem. Our emphasis is why do we do certain things and how do we do it. We comment that many legacy modems are sub optimal because they incorporate a number of compromises that were appropriate for the time the compromises were invoked. Today, we have access to a wider range of tools and resources that when applied to the design of a modern modem leads to systems that far outperform legacy receivers. To be better able to appreciate the processing performed in a modern modem we will follow the development of early and recent modem architectures.

Coordinator and Lecturer

fredric j. harris, PhD, Cubic Signal Processing Chair Professor of Electrical and Computer Engineering, San Diego State University, California. Dr. harris is a recognized expert in the field of Digital Signal Processing (DSP), especially as applied to underwater acoustics, radio surveillance, satellite communications, radar, real-time acoustics, vibration monitoring equipment, and laboratory instrumentation. He is the author of the text, Multirate Signal Processing for Communication Systems. Since 1970, he has been a consultant to such organizations as the U.S. Navy Ocean Systems Center, Lockheed, ESL, Cubic, Hughes, BAE, Scientific Atlanta, Rockwell, Northrop Grumman, Boeing, and Inritsu. He also has presented courses on fast algorithms, adaptive algorithms, error-correcting codes, and control theory. Dr. harris has conducted seminars in DSP for Motorola, Northrop Grumman, BAE, Lockheed, Hewlett Packard, General Electric, Rockwell, Spectral Dynamics, and the U.S. Navy Research Laboratory.
