摘要：
We propose a new structure for spectrum sensing which employs multiple energy detectors in multiple antenna system, in order to enhance its reliability. The performance is investigated by simulation and compared to that of the conventional energy detector. The simulation result shows that the performance of the proposed scheme is much better than that of the conventional one. Additionally, the performance is described in terms of ROC curve.
