Original Abstract

A cooperative spectrum sensing (CSS) scheme forcognitive radio network (CRN) is proposed in this paper. The energy values from different cognitive radios (CRs) are used to perform the soft combining operation. More precisely, we analyze the performance of CSS with several soft data fusion schemes: square law selection (SLS), maximal ratio combining (MRC), square law combining (SLC), and selection combining (SC) in Nakagami-n (Rician) fading environment. Towards that, an expression of detection probability in closed-form for each soft data fusion scheme in Rician fading channel is derived. A comparative performance of soft data fusion schemes has been illustrated for different network and channel parameters. Further, the performance comparison between soft data and hard decision combining schemes (such as majority-rule, AND-rule, and OR-rule) is also investigated
