Performance Analysis of Suboptimal Spectrum Sensing Algorithm in Cognitive Networks

Recently, both optimal and suboptimal spectrum sensing approaches have attracted extensive attention in wireless communications field. Thanks to opportunistic spectrum access schemes, different cognitive users can cooperatively search for and exploit instantaneous spectrum availability. In this paper, we address the analysis of spectrum sensing in opportunistic spectrum access models and then determine throughput of the cognitive radio system. Our goal in all designs is reach optimal access policy for each channel with the high cooperative sensing performances.
