L. Bin, THE LEAST-SQUARES DOUBLE-PHASE-DIFFERENCE SEQUENCE ESTIMATION FOR CONTINUOUS-PHASE MODULATION, IEEE transactions on communications, 43(2-4), 1995, pp. 1265-1268
The least squares double-phase-difference sequence estimation (LS-DPD-
SE), as a robust way of demodulating continuous phase modulation (CPM)
signal subject to frequency variation such as Doppler frequency shift
, is presented in this paper. The applications to Gaussian minimum shi
ft keying (GMSK) and continuous phase frequency shift keying (CPFSK) a
re considered.
