ROC curve for Likelihood ratio

Latest activity Commented on by gari mah on 8 Dec 2018
I want to plot the ROC curve at a specific SNR for the likelihood fusion rule which is a function of rayleigh fading channel gain and the probability of detection and probability of false alarm .
How I can do that ?:

With the plot() command.
If you want a more detailed than that, maybe you could post significantly more detailed question, perhaps along with code for the parts you have already managed to do?

I am trying to implement Cooperative sensing for cognitive radio system, wherein I am taking double thresholds (high and low) for better detection. I want to know how can I incorporate a Fusion decion centre? I mean how to send one bit and 2 bit decisions and get final results based on their OR or AND operation.
