On the Energy Detection of Unknown Signals Over Fading ChannelsAbstract—This letter addresses the problem of energy detection of an unknown signal over a multipath channel. It starts with the no-diversity case, and presents some alternative closed-fo

This code plots the receiver operating characteristics (ROC) curve for Rayleigh channel. The formulas for the probability of detection and the probability of false alarm are taken the following paper: Digham, F.F. Alouini, M.-S. Simon, Marvin K.,
