<p>The IEEE 802.16a standard provides for Broadband Wireless Access (BWA) for the global deployment of broadband Wireless Metropolitan Area Networks (WMANs). Commercially known as Wi-Max, the standard aims to provide large amounts of wireless data over long distances, in a cellular type structure with base stations and subscriber stations. The standard uses Orthogonal Frequency Division Multiplexing (OFDM) which allows the transmission of high data rates in severe channel conditions without complex filters. This thesis tested the performance of a developed partial band jamming algorithm on a modified 802.16a standard. The partial band jamming was applied to 1/8, * and * of the total subcarriers. Additionally, both intentional and unintentional interference were added to the signal. The modified code repeated the signal 48, 96, or 192 times and recombined the data using Maximal Ratio Combining. This thesis explored the potential for performance gains by reducing the data rate with a repetition code. The evaluation was performed in MATLABÂ®.
