Hi everyone

I think I've post in the wrong forum yesterday, so here is my problem.

I have to make a matlab program in order to draw the IQ diagram for some signals as BPSK and QPSK.
I have to correct the Doppler effect and the phase shift with PLLs. I think Costas loops are good for correcting the phase shift.
But what about the Doppler effect ? What have I to do to correct it ? Should the processing be before or after the Costas loop for phase shift ? Or is there some processing allowing to correct both shift phase and Doppler effect ?

I don't know if I'm clear enough (sorry my English is not very rich)

Thanks in advance
