| 摘 要： | 在Nakagami衰落信道下，分析了认知无线电网络中等增益合作检测的性能. 将检测概率表示式中的多重积分转化为一重积分，并利用广义马库姆Q函数的等价表达式，得到了检测概率的级数表达式，并给出一组实际应用中的参数设置，仿真结果验证了理论分析结果的正确性. 推导得到的检测性能表达式可以为设计认知无线电网络提供参数选择.

| Abstract: | The performances of cooperative spectrum sensing with equal gain combination over Nakagami channels are analyzed in cognitive radio networks. The series form of detection probability is derived by transforming the multiple integral to a single integral and using the equivalent representation of generalized Marcum Q function. Simulation shows that the correctness of the theoretical analysis results are validated, and a group of practical parameter settings is given. Parameter selection for designing cognitive radio networks can be provided by expressions of detection performance. |
