一种适用于认知无线电系统的盲感知算法

Blind Sensing Algorithm for Cognitive Radio

频谱感知是认知无线电中最具挑战的问题之一。提出一种基于信号协方差矩阵特征值的盲感知算法,仿真显示这种方法有较好的检测性能,适用于认知无线电系统中授权用户的检测。

Spectrum sensing is one of the most challenging problems in cognitive radio. In this paper, a sensing algorithm based on the eigenvalue of the sample covariance matrix is proposed. Simulation results show that, the proposed algorithm does a better job. The algorithm is particularly useful for the cognitive radio system.
