摘要
针对认知无线电通信系统中基于能量检测的频谱感知方法,分析了基于能量检测法的高斯和瑞利信道下的检测概率和虚警概率,进行了MATLAB仿真,得到了理论和仿真曲线,结果表明能量检测法在确知噪声的情况下是一种有效频谱感知方法。
This paper introduces spectrum sensing technology based on energy detection in cognitive radio .The detection probability and false alarm probability are discussed based on the Gauss and Rayleigh fading channels.By MATLAB simulation, the theory and the simulation’ s curve were deserved.The re-sults show that energy detection method is an effective spectrum sensing method of the determined noise situation.
