Modeling and analysis of cooperative spectrum sensing is an important aspect in cognitive radio systems. In this paper, the problem of energy detection (ED) of an unknown signal over Nakagami-m fading is revisited. Specifically, an analytical expression for the local probability of detection is derived, while using the approach of ED at the individual(More)
—The cooperative spectrum sensing in cognitive radio (CR) environments is generally modelled as a distributed binary hypothesis testing problem. However, modelling of the system in presence of correlated multipath-fading is an important issue. It deals with complex dependencies of large number of random variables. Earlier developments on decision fusion(More)
