The emergence of WiMAX has attracted significant interests from all the fields of wireless communications including students, researchers, systems engineers and operators. The WiMAX can also be considered to be the main technology in the implementation of other networks like wireless sensor networks. Developing an understanding of the WiMAX system can be best achieved by looking at a model of the WiMAX system. This paper discusses the model building of the WiMAX Physical layer using computer Matlab 7.5 version. This model is a useful tool for BER performance evaluation for the real audio data communication by the WiMAX Physical layer under different channel encoding rates, digital modulation schemes and channel conditions.
