A STUDY ON SPECTRUM SENSING METHODS OF COGNITIVE RADIOKeywords: Cognitive Radio (CR) , Primary User (PUs) , Wide Sense Stationary (WSS) , Auto Correlation Function (ACF) , Power Spectral Density (PSD) Abstract: Cognitive radio (CR) is a promising technology which avoids congestion in wireless communication by exploiting unused radio spectrum. The Spectrum sensing (SS) plays a fundamental requirement of CR which finds an unused free spectrum and detects the licensed user transmissions. This paper constitutes the study about the classification of spectrum sensing in energy detection, cyclostationary, matched filter, MRSS.
