Abstract
The present invention provides a signal demodulation method and device. The method includes: obtaining a symbol probability parameter, where the symbol probability parameter comprises: an amplitude rand a phase angle φof a receive signal, an amplitude rand a phase angle φof each constellation point xin a decision constellation point set, and a standard deviation σof Gaussian noise and a standard deviation πof phase noise; calculating, according to the symbol probability parameter, a symbol probability that a transmit signal is each constellation point xin the decision constellation point set; and performing demodulation according to the symbol probability, and outputting demodulation information. The present invention improves an anti-phase-noise capability.
