Hi
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?

If not provide some code of what you have tried, equations etc.

Hi,
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.
