Thank you for your answer. I'm trying to receive information from satellites. I'm trying to use different modulations and different frequencies. I'm working at UHF that has a doppler of ~10kHz, and at S band with ~60kHz. In my system I have a costas loop and pll for the synchronization...

Thank you very much for your answer. The problem is that I don't know how to apply this to my particular project. I'm trying to receive a 250kHz BPSK modulated signal. The signal is transmitted in UHF (345MHz). If the doppler is, let's say, 10kHz at a certain moment, I know that my carrier...

Hello, If been for a while trying to find information about how Doppler effect affects modulated signals. When a transmitter is moving relative to a receiver, the receiver will have a shift in the carrier frequency that will vary as the transmitter gets closer or moves away from the...
