ECE 642 – Communication Systems I


Description                                 

Principles of communication theory applied to the representation and transmission of information. Topics include analysis of deterministic and random signals, amplitude modulation, angle modulation, analysis of noise, basics of digital communication systems, matched filter and error probability.

Prerequisites

Basic knowledge of signals and systems, including Fourier analysis, and of probability and random processes.

Corequisite: ECE 673.
