Simulation and assessment of WiMAX network performance in different environments
Nowadays, WiMAX has become one of the candidate networks in order to achieve high speed Internet via wireless access systems .In this paper, the broadband wireless access system provided by IEEE802.16 and its modification for mobile customers IEEE802.16e will be addressed .Exclusively the downlink data transmission will be considered .the system performance will be tested in different operating environment. Rayleigh fading channel, channel estimation and equalization are considered also partial and full usage of subcarriers will be investigated with the support of cyclic prefix implementation. In addition the proposed simulation model has been tested using a Stanford channel model.
