Wireless Communications

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.
