Spectrum Sensing in Cognitive Radio using Bayesian Approach

Anuja A. Kokil, A. M. Patki

Abstract: In this paper on the basis of probability of detection and probability of false alarm the performance of suboptimal detector is analyzed. To maximize the spectrum utilization Bayesian Detector is proposed. This method makes use of prior statistics and signalling information of primary user to improve secondary user throughput and spectrum utilization of both primary user and secondary user.
