An ever crowed Radio spectrum system implies that future demands must be met using more data throughput wireless technologies. Since system bandwidth is limited and user demand continues to grow. This problem could be solved by WiMAX (Worldwide Interoperability for Microwave Access) technology based on the IEEE 802.16 specifications. Since it offers high level of services. In this paper the performance of Turbo Coded WiMAX system over different Channels like AWGN, Rayleigh & Rician has been analyzed. And the performance of each channel is compared with the performance as was with convolution code (without Turbo) and performance at different iterations in Turbo code.
