Cyclostationary Signal Processing using cyclo autocorrelation function

Hi all,

I working on signal processing.. I have a PCG signal which is cyclo stationary by property. There is cyclic rhythmic variations in the signal. I do want to find out the cycle frequency. I have studied a paper which states that using cyclic auto-correlation function and spectral correlation density one can find out the cyclic period.

Can any one having any Idea about this and I gone through the theory of this analysis but implementing in matlab facing some problems. I have done autocorrelation which is periodic but for calculating spectral correlation density one has to find out the fourier series coefficients. I am not able to code for calculating fourier series coefficients. Can anyone help me. Thanks in advance.
