Course Overview

Course in a Nutshell

The course begins with a review of the modulation schemes, RF propagation issues, performance enhancement techniques, and multipath mitigation methods.  This is followed by a discussion of the principle of OFDM, IEEE 802.16 physical layer, and WiMAX signalling.  The course concludes with a look at the network architecture and link budget calculations.
