Phase offset estimation of SOQPSK waveform by the analysis of the angle distribution

International audienceIn this paper, the problem of phase synchronization is investigated for the shaped offset quadrature phase shiftkeying (SOQPSK) waveform, a highly bandwidth-efficient modulation. We propose a phase offset estimation algorithmbased on the angle distribution analysis of the signal. Simulation results show that the algorithm is capable of correcting largephase offsets in the presence of high noise level even with using a short pilot sequenc
