对合作频谱检测的AND准则和OR准则频谱检测算法进行了理论分析,对2种检测算法进行了单用户和多用户的理论仿真和蒙特卡洛仿真。仿真结果表明,这2种检测算法正确检测概率与用户数的关系符合信号的统计分布特性结果,误差随虚警概率的增大而逐渐变小；对相同用户数,OR准则的检测概率高于AND准则检测概率。这一结论可以为认知无线电合作式频谱检测策略的选择提供一定指导。

Spectrum detection algorithm of AND guidelines merger and OR guidelines merger were analyzed in theory, theoretical simulation and Monte Carlo simulation were done for two kinds of detection methods for the single user and multi-user. Simulation results show that the relationship between detection probability and users of the two kinds of de-tection algorithm conform to the statistical distribution characteristics of signal,the error of the Monte Carlo simulation and the theory simulation results decreases along with the augment of false-alarm probability gradually;The detection probability of OR guidelines merger is higher than the AND guidelines merger under the same number of users. This conclusion can provide guidance for choice of detection strategy of cognitive radio cooperation type spectrum.
