Improved p-norm energy detector in Generalized κ-μ fading channel for spectrum sensing in cognitive radio

The classical energy detection (CED) system is a well known technique for spectrum sensing in cognitive radio. Generalized p-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 highlights the combined benefit of the p-norm energy detector and the improved algorithm for spectrum sensing in achieving a higher performance gain in AWGN and generalized κ-μ fading channels scenario over the CED scheme.
