Class 3. P: ECE 440 or graduate standing. Introduction to digital
communication systems and spread spectrum communications. Analog
message digitization, signal space representation of digital signals,
binary and M-ary signaling methods, detection of binary and M-ary
signals, comparison of digital communication systems in terms of
signal energy and signal bandwidth requirements. The principal types
of spread-spectrum systems are analyzed and compared. Application of
spread spectrum to multiple-access systems and to secure communication
systems is discussed.
