BER PERFORMANCE IMPROVEMENT OF IEEE802.22 (WRAN) OVER AWGN CHANNEL USING MIMO TECHNOLGY

T he WRAN technology is useful for remote access to grid computer sites and to independent operating in developing countries ruler or non - metropolitan areas. WRAN specification are define by the IEEE 802.22 working committee. In this paper an overview of the standard and more specifically its physical layer is introduced. In order to evaluated the performance of the system. We model of the physical layer in MATLAB/SIMULINK.
