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.
Under the Nakagami fading channel, the performance of cooperative detection of equal gain in cognitive radio networks is analyzed.The multiple integrals in the detection probability expression are transformed into one integral, and the equivalent expression of the generalized Markham Q-function is used to obtain the detection Probability expressions are given, and a set of parameter settings are given in practical application. The simulation results verify the correctness of the theoretical analysis results. The derived detection performance expressions can provide parameters for the design of cognitive radio networks.
