Hi all,

I am a student from India doing masters in communication systems. I have an issue with implementing an idea in matlab. Please check if you can help with it.

My course project deals with "Cooperative Spectrum Sensing using Cyclostationary Feature Detection in Cognitive Radio for Ultra-Wideband Communication". I selected this topic since it is an emerging topic and there is good scope for further research.

I already completed the Spectrum Sensing using Cyclostationary Feature Detection and successfully applied it to the Ultra-Wideband section. I also have the codings for the Cooperative part but find some mistakes there.

I have myself defined the pfa(probability of false detection) values from 0 to 1 and I think there I made the mistake. Now what i require is an idea regarding how to introduce "pfa" into the program. So if you have any false detection program please mail it to me. Or even a simple idea will do. I will try and convert the idea into codings.I aim to plot the ROC. ie probability of detection against probability of false alarm.

I would be very thankful for your reply.

Hello !

I am also student of Master of Engineering in Communication Engineering. My Dissertation Topic is Spectrum Sensing using Cyclostationary Detection. I want to do comparative analysis of at least 2 algorithms to get ROC in Cyclostationary Detection using MATLAB. I am not getting output. Please help me.
