ENEE 720: Wireless Communication Theory

Course Goals:

The main goal of this course is to introduce the students to the multiple-user communication theory. The most prominent application of this theory is the physical layer of CDMA wireless communication networks. The course starts with a review of the single-user communication theory, introduces the distinguishing features of wireless communication channels, such as fading and multiple-access interference, establishes the weaknesses of single-user detection techniques when used in multi-user systems, introduces and investigates in detail the optimum multi-user detector, and then presents low-complexity suboptimum multiuser detectors such as decorrelating detector, MMSE detector and decision-feedback detector. This course also studies the physical layer techniques of diversity reception/transmission, multiple transmit/receive antennas, and beamforming.
