Abstract

The double threshold based cognitive radio system is very efficient towards having the high detection probability but lacks in the proper utilization of the confused region between the two thresholds. This paper proposes an improved spectrum sharing (ISS) scheme which does not only provide the higher detection probability but also utilizes the confused region in a productive and risk-free manner. Moreover, the proposed scheme achieves better throughput than the conventional cognitive radio (CCR) system based on the single and double threshold, both. To further achieve the improved results, the proposed system has been analyzed for the case of novel cognitive radio system, where, the obtained results are found beyond the sensing-throughput tradeoff and are better than the CCR system. We have further implemented the ISS scheme under the cooperation of n-out-of-k CRs, this cooperative approach makes the proposed system robust enough towards the hidden terminal problem and “shadowing and fading” effects of the wireless communication channel.
