Claim 6:
7. A phase shift keying modulation method, the method comprising:
mapping a binary data stream to be modulated into a phase sequence, the phase sequence including one or more phase symbols according to a mapping relationship between the binary data stream and the phase sequence in a predetermined phase shift keying modulation mode;
modulating the phase symbols 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 symbols modulated in the symbol cycle; and
obtaining a radio frequency signal by modulation based on the phase signal.
