在不同信噪比的情况下，对在agwn的信道的仿真利用能量检测，形成roc曲线。-Agwn the channel simulation in the case of different signal-to-noise ratio, energy detection, the formation of the roc curve.

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.,
