Abstract

The classical energy detection (CED) system is a well-known technique for spectrum sensing in cognitive radio application. Generalized \(p\)-norm detector for spectrum sensing 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 detector and an improved algorithm for spectrum sensing in achieving a higher performance gain.
