Course Description

This course covers various basic topics in wireless communications for voice, data, and multimedia. It begins with an overview of current wireless systems and standards, followed by a characterization of the wireless channel, including path loss, shadowing, and the flat vs. frequency-selective properties of multipath fading. It then examines the fundamental capacity limits of wireless channels and the characteristics of the capacity-achieving transmission strategies. This part is followed by practical digital modulation techniques and their performance under wireless channel impairments, including diversity techniques to compensate for flat-fading, multicarrier modulation to combat frequency-selective fading, and an introduction to multi-antenna communications. The course concludes with a discussion of various practical multiple access schemes in wireless cellular systems.

Prerequisite

Digital Communications,Linear Algebra, Probability.

Course Objectives

The course is designed to elaborate on the underlying theory, design techniques as well as analytical tools of wireless communications.

Students are supposed to understand characteristics of the wireless channel (e.g. fundamental capacity limits), various modulations, coding, and signal processing schemes such as state-of-the-art adaptive modulation, multicarrier, spread-spectrum, and multiple-antenna techniques. This course will help students to design multiuser communications systems, cellular systems, and ad hoc wireless networks.
