Simulation and Performance Analysis of Efficient Wireless Channel in WiMAX MIMO Using Real Time Data Transmission

Vaidehi J. Sojitra, Dr. Bhavin S. Sedani

This paper presents the simulation and performance evaluation of WiMAX MIMO (worldwide interoperability for microwave access) system along with efficient wireless channels using real time data transmission. In order to visualize and understand the effects of real time environment over system performance, it is essential to analyze the real time fading channels i.e. Rayleigh channel and Rician channel. As in the real life scenario it is not possible to have unified distribution of fading over the entire communication channel. The present paper enhances the current status of WiMAX MIMO system along with the modelling of suitable wireless channels i.e. AWGR, Rayleigh and Rician in order to control BER of the system. Further with the variation of different channel parameters for real time data transmission through WiMAX MIMO system, the structure compatible to practical scenario can be implemented through this, Modelling using antenna diversity principles in order to control BER of the system. The central objective of this paper is to built up the real time model for the WiMAX MIMO system along with the suitable wireless channels compatible to various atmospheric conditions for the signal propagation.
