  • Summary Quadrature Phase Shift Keying (QPSK) is the preferred modulation scheme for satellite data communication. A two stage estimation scheme for the demodulator for processing satellite data is proposed in this paper, where carrier frequency estimation is followed by timing recovery under training. Frequency offset estimation is performed by finding the slope of the best fit line through the unwrapped phase. Since this carrier frequency estimation technique gives an approximate estimate of… CONTINUE READING
