提供一个cell-weraging constant false alarm rate (CA-CFAR)的算法，基于信号检测的方法。-We present a method for evaluating the performance of cell-weraging constant false alarm rate (CA-CFAR) processors which use the anplitude of echo signals rather than their squ

认知无线中的能量检测，仿真了高斯信道和瑞利信道的检测概率、虚警概率与判决门限的关系曲线以及两者之间的关系曲线-The detection probability, false alarm probability and the decision threshold of the Gauss channel and the Rayleigh channel are simulated by the energy detection in cognitive radio.
