I would like to know if it is possible to search Doppler shift of a carrier with sufficient oversampling while performing code search in the freqency domain. For instance can I selectively drop every X time domain sample bin from the fft processing? Will that not effectively change the input frequency being compared to the locally generated code?
I would like to perform the Doppler shift search of digital satellite broadcasts without having to change the lo supplying the IF in hardware.
Can this be done this way?
