Energy Detection Simulation: Rayleigh Channel

This code simulates ROC curve for the energy detection in Rayleigh channel.

The code simulates the energy detection in cognitive radio when the sensing channel at the secondary user is Rayleigh flat-fading channel. The detailed comments are written in the code. The reference paper used for the energy detection theory is "Unveiling the Hidden Assumptions of Energy Detector Based Spectrum Sensing for Cognitive Radios," IEEE Communications Surveys and Tutorials.
