hi, I am doing project on spectrum sensing in cognitive radio, i have implemented basic program for energy detection technique, but i'm struck with code for cyclostationary detection. i am confused how to assume the cyclic frequency parameter for the detection of random signal...and is there any restriction on assuming primary user signal.... can anyone please suggest ......

For digital modulated signal with symbol duration Tb, cyclostationary features exist at α = k/Tb and α = ±2fc + k/Tb , where fc is the carrier frequency, and k is an integer.

check this matlab code https://www.mathworks.com/matlabcentral/fileexchange/16742-frequency-estimation---baud-rate-estimation
it uses cyclo stationary methods
