EE 421 - Digital Communication Systems

3 lecture hours 0 lab hours 3 credits
Course Description
This course covers important concepts and signaling techniques commonly used in digital communication systems. Pulse modulation methods including PAM, PWM, and PPM are studied. Digital modulation methods including ASK, FSK and PSK modulations are reviewed, and modulation techniques such as QAM are presented. Random processes are used to model noise. The effects of noise on bit-error probabilities are analyzed for various systems. Other topics covered include the matched filter receiver, correlation receiver, and an introduction to error-correction coding. (prereq: EE 4021  or EE 4022 )
