- binary phase shift keying. It is one of the ways to transform analog signals into data values, and to use the complex wave combination that deviates from the phase to show the information key shift phase mode. BPSK uses a sine wave and a phase reversal wave to make one party 0 and the other side 1, so that 2 values (1 bits) can be transmitted at the same time.
