Course Overview

Course in a Nutshell

The course begins with a review of the 3G cellular systems, modulation techniques, RF propagation channel modeling issues, performance improvement techniques, and multipath mitigation methods.  This is followed by a detailed discussion of the principle of OFDM, IEEE 802.16 physical layer, and WiMAX signaling.  The course concludes with a study of the network architecture, mobility use cases, system performance issues, and a link budget example.
