Abstract: The performance of spectrum sensing based on cooperative relaying is investigated. It is found that multiple number of cognitive relay nodes improve spectrum sensing performance. It is shown that the optimal sensing time of CR reduces with the increasing number of relay nodes. Reduction in optimal sensing time results in increase of the optimal throughput of the CR significantly. Impact of SNR on optimal throughput and on sensing time is noticeable. If SNR increases, the normalized optimal throughput increases and optimal sensing time reduces for a fixed number of relay nodes.
Keywords: SNR, CR, BER, Spectrum Sensing.
