Claim 15:
16. A phase shift keying modulator method, the method comprising:
mapping a binary data stream {bn} into a phase sequence {θk}, the phase sequence {θk} including one or more phase symbols;
modulating the phase symbols in the phase sequence into a continuous phase signal φ(t) through a phase function according to: ϕ(t)=Σk=0K−1θk*p(t−k*T); and
obtaining a radio frequency signal based on the continuous phase signal;, wherein n=0, 1, 2, 3, . . . N−1, k=0, 1, 2, . . . , K−1, N and K are positive integers, p(t) is the phase function, and p(t≤0)=0, p(t≥T)=1, a value of p(0≤t≤T) changes continuously between 0 and 1, t is time variable, and T is a symbol cycle.
