EE 121. Introduction to Digital Communication Systems
Catalog Description: (4 units) Introduction to the basic principles of the design and analysis of modern digital communication systems. Topics include source coding, channel coding, baseband and passband modulation techniques, receiver design, and channel equalization. Applications to the design of digital of digital telephone modems, compact disks, and digital wireless communication systems. Concepts illustrated by a sequence of MATLAB exercises.
Prerequisites: EECS 120, 126.
Course objectives: The students should be capable of choosing an appropriate modulation system for a given application, do a comparative analysis of the noise performance of different modulation systems, and design appropriate receiver structures to achieve given design goals. Students learn some of the most important data compression algorithms used in practice. Students learn some of the most fundamental error control coding and decoding schemes used in practice.
