Abstract

Spectrum sensing is a very important function of cognitive radio to prevent harmful interference with licensed user. In order to increase the usage level of the spectrum holes while maintaining seamless wireless connectivity spectrum sensing must be used. There are several techniques to sense the spectrum. In this paper, one of the popular technique energy detection is investigated. This involves multiple cognitive radios cooperation, coordination and collaboration to detect spectrum holes through energy detection.To achieve this, the optimal data fusion rule is derive. Optimal voting rule and detection threshold are investigated to minimizes the total error rate probability in cooperative spectrum sensing. The proposed method improve the performance of spectrum sensing and increases spectrum utilization.
