摘要

为获得最佳感知，系统在n个备选用户中选择最佳中继进行协作感知。但实际系统可能由于各种原因选择了第二佳或乃至更为一般的第N佳中继。为此，提出基于第N佳中继选择的协作频谱感知，推导了其在瑞利平坦衰落下的检测概率，并给出闭合表达式。数值计算表明，随着N的增加，系统检测概率不断下降，乃至低于任意选择；随着n的增加，基于最佳或接近最佳选择的系统检测概率明显提高，而基于最差或接近最差选择的系统检测概率则有所下降。

Abstract

In the cognitive radio system

the optimal relay would be selected from the n available ones to obtain the best sensing performance.However

in actual systems

the secondary or even the more general N

best relay may be selected for various reasons.Therefore

the cooperative spectrum sensing based on the N

best relay selection was proposed.The closed-form expression of the detection probability was derived in Rayleigh fading channels.Numerical results show that the detection probability declines continuously even below the one of the arbitrary selection as N increases

and that the one based on the optimal or suboptimal selection increases obviously but the one based on the worst or near worst selection decreases slightly as n increases.
