A POWER AND SPECTRAL EFFICIENT MODULATION ROBUST TO PHASE NOISE

摘要

The paper proposes a differential continue phase modulation, which is robust to phase noise with high power andspectral efficiency. In modulation, a set of baseband signal is first designed to be quasi constant envelope withcontinue phase shift over the symbol duration. Modulation is realized by choosing a signal from the baseband signalset based on input bits and phase state. Receiver only needs to calculate the phase shift cumulant of signal over thesymbol duration. Thereby, the performance of demodulation is immune to the phase noise caused by local oscillators,relatively large Doppler spread and so on.
