Analysis of WiMAX Physical Layer With MAC/PDU

The emergence of WiMAX has attracted significant interest from all the fields of wireless communication including students, researchers, system engineers and operators. Developing an understanding of the WiMAX system can be best achieved by looking at a model of the WiMAX system. Standards from IEEE and ETSL have been used to develop this model. The model presented in this paper built with generic MAC PDU processed by the Physical Layer convolution encoding with QPSK modulation and transmitted with 256 carrier OFDM symbols. The trend of wireless and in addition of internet everyone wants the higher speed and mobility. So one must require wireless broadband networks with higher data rates. WiMAX will give the solution of higher data rate and 7 to 11 Km mobility. In this paper we deal with the physical layer of WiMAX system. This model is very useful to analyse the WiMAX system. We use OFDM and OFDMA for WiMAX system to get better performance and mobility with higher data rate. Keywords—Wireless Broadband, WiMAX, Modulation, Coding, OFDM, Physical Layer.
