The spectrum available for the wireless services is limited; the increased demand of wireless application has put a lot of constraints on the utilization of available radio spectrum. For the efficient spectrum utilization for wireless application IEEE 802.22 standard Wireless Regional Area Network (WRAN) is developed, which is based on cognitive radio technique that senses the free available spectrum. In this paper, the authors are evaluating the performance of WRAN over physical layer by using QPSK modulation over Rayleigh fading channel and obtaining the Bit Error Rate (BER) curves.
