Cooperative sensing is a way of improving the performance of spectrum sensing by exploring the spatial diversity in cognitive radio networks. One of the critical parameters of cooperative sensing is the estimation of optimal sensing time over probable channel noise impediments such as AWGN, Rayleigh, and Rician fading. In this paper, the optimal sensing time is evaluated for single node as well as...
Cooperative sensing is a process of getting spatial diversity gains to improve the performance of system over impaired cognitive radio networks (CRN). In this paper, an improved generalized extreme studentized deviate (IGESD) method is proposed for effective cooperative sensing, where the algorithm checks the normality of the soft decision data using Shapiro-Wilk (SW) test and estimates the expected...
