How can we synchronized symbols for P25 C4FM demodulation?

In case of P25 C4FM demodulation , how can we synchronised the signals in matlab so that we should know exactly the point at which the received signal is getting started ?

In LiquidDSP , it is given like this - https://github.com/jgaeddert/liquid-dsp/blob/master/examples/symsync_crcf_example.c

Hi Shubham,

I understand that you wish to know about synchronizing signals in MATLAB to know the point at which received signal is getting started.

You can perform this finding ‘peak’ of the correlation result between the received signal and the synchronization pattern.

‘xcorr’ function and ‘corrcoef’ function might be helpful to you. Below is the link to their documentations:
