摘要：
In this paper, a maximum eigenvalue based primary user (PU) signal detection algorithm for cognitive radio (CR) with multiple antennas is proposed. In the proposed detection algorithm, manifold of the PU signal are integrated at the receiver of multiple antenna CR to obtain the covariance matrices of the signal and noise. The expressions of threshold and probability of false alarm for the detector are derived. Experimental results are reported to demonstrate that, in comparison to the CR with single antenna, the CR with multiple antennas performs much better.
