Title
Performance Analysis of Multi-hop Relay Cooperative Spectrum Sensing.
Abstract
This paper analyzed the performance of multihop relay cooperative spectrum sensing. The closed form expression of the upper bound of the detection probability of multi-hop relay cooperation is derived in Rayleigh flat fading channel. It provides the theoretical basis for analyzing the performance of multi-hop relay cooperative spectrum sensing. Simulation results show that the detection probability decreases as the increase of the hop number when each hop sub-channel has the same average signal to noise ratio (SNR). The detection performance of three-hop relay cooperative spectrum sensing outperforms that of twohop relay when both SNRs of the last two hops in three-hop relay are 3 dB bigger than the SNR of the second hop in two-hop relay. © 2012 ACADEMY PUBLISHER.
