This thesis investigates three approaches to implement the OFDM functions of the fixed-WiMAX standard on reconfigurable platforms. The custom RTL approach showed the ability of a medium size FPGA to accommodate the design with only 50% occupation rate. The AccelDSP approach showed an area overhead of 10%. However, the throughput obtained was almost 1/4 of that obtained in the custom RTL approach. The Tensilica Xtensa processor approach presented remarkable figures, in terms of power, area and
