基于循环谱的中继合作频谱检测方法
Detection Method for Relay Cooperative Spectrum Based on Cyclic Spectrum
摘要
Abstract
Combining advantages of cyclic spectrum sensing with advantages of relay cooperative sensing, this paper proposes cyclic spectrum detection method in fading channels. Considering different channels' channel gain and correlation between cognitive users jointly, the two users cooperative channel model is constructed, and test statistic expression is also given. Based on the above results, it discusses relay cooperation of multi-user network, and it makes detection performance simulation. Simulation results show, when the false alarm probability is small, detection probability and detection agility through relay cooperation both improve significantly, and agility gain decreases with the distance between two cognitive user increases.关键词
