Doppler frequency shift is often phenomenon in communication, personal understanding of the doppler signal carrier frequency change caused by the receiving end, then the receiver signal processing should be adjust the carrier offset, see a lot of literature writing is the signal resampling, so want to ask everybody here doppler frequency shift is changed carrier frequency or sampling frequency, or how the relation between both, how to understand? thank you

CodePudding user response:

Sampling rate without changing, need to change the receiver carrier frequency

CodePudding user response:

The signal resampling is unlikely to solve the problem, must get the frequency offset estimation and offset,
Doppler frequency shift is a relatively simple question, complex or doppler spectrum spreading problem, this time different multipath components with different deviation, not simple to correct,
