With the development of wireless and mobile Internet technology, people in everyday life and business hope for access to the Internet even while they are in movement. IEEE 802.20 technology is mobile and can effectively address high-speed network access. In this paper the PHY layer model for simulating 802.20 in SIMULINK and subsystems in MATLAB S-function files are presented. To evaluate the performance of the proposed system implementation, the mobile channel models have been developed and the system is tested in different channel conditions, whereas different modulation schemes supported in this standard are analyzed. Bit error rate (BER) versus signal to noise ratio (SNR) curves are used for comparing the results.
