Abstract
The present invention provides a phase shift keying modulation method and a corresponding modulator, a phase shift keying demodulation method and a corresponding demodulator. The phase shift keying modulation method comprises: mapping a binary data stream to be modulated into a phase sequence comprising one or more phase symbols according to a predetermined phase shift keying modulation mode; modulating the phase symbol with a preset phase function to obtain a phase signal that changes continuously with time, wherein in each symbol cycle, a difference between a value of the phase signal at a beginning of the symbol cycle and a value of the phase signal at an end of the symbol cycle is equal to the phase symbol modulated in the symbol cycle; and obtaining a radio frequency signal by modulation based on the phase signal.
