Abstract

The classical energy detection (CED) system is a well-known technique for spectrum sensing in cognitive radio. Generalized -norm detector for spectrum sensing in additive white Gaussian noise (AWGN) has been shown to provide improved performance over CED under certain conditions. Further, improved algorithm exists which works better than the classical energy detection algorithm. The present paper takes into account the combined benefit of the -norm energy detector and the improved algorithm for spectrum sensing for individual cognitive user in a cooperative spectrum sensing system to achieve a significant performance gain in both AWGN and generalized − fading channels over the cooperative/ non-cooperative CED scheme.

Keywords: -norm energy detector Energy detection Cooperative spectrum sensing Cognitive radio − fading channel
