Abstract

In this paper, we investigated the important influence of reporting frame format in cooperative spectrum sensing (CSS), which was ignored in existing works. Firstly, we proposed a comparison between soft and hard combination schemes based on the practical reporting frame format. Furthermore, we derived the closed-form expression of optimal cooperative nodes in soft combination under the practical reporting condition. The theory analysis and simulation results show that the results of existing works would not hold when considering the real reporting frame format, and the optimal performance of CSS would be obtained when the sampling time equals to the reporting time.
