Doppler shift compensation techniques for LEO satellite on-board receivers
In this paper two techniques employed for compensating the Doppler shift encountered in LEO satellite receivers are presented. These include the analog compensation technique involving the carrier tracking loop and the compressive receiver technique. The compressive receiver technique which involves precise detection of the rapidly time varying carrier frequency received by the satellite receiver is discussed in further detail. A compressive receiver with a center frequency of 100 kHz and a Doppler shift up to ±100 kHz is simulated on MATLAB to test the technique.
