Cognitive Radio is an intelligent radio that exploit electromagnetic spectrum opportunistically by using different techniques.The critical task is to sense the free spectrum and using it.In past few years many sensing schemes have been proposed to sense the availability of free spectrum.In this paper, Energy Detector technique of spectrum sensing is reviewed.The results have been simulated for Probability of False Alarm, Probability of Detection and Probability of Missing detection for the Energy Detector.
