Description
Summary:The current regulation of static spectrum distribution is a key factor that results in underutilization of fruitful wireless spectrum. Cognitive transmission must be predetermined to resolve the problems in the future network. In this paper, two kinds of cognitive channel, which are mutual interference cognitive channel with and without cognitive relay, will be modeled and analyzed. In mutual interference channel, the secondary system attempts to transmit its own data without degradation of primary system's performances. In cognitive relay channel, a relay is induced to improve throughput of the secondary system. Simulation results are presented to compare performance of both schemes.
