One of the ways to convert analog signal into data value is to use complex wave combination which deviates from phase to express information keying phase shift. BPSK uses the sine wave of the reference and the wave of phase reversal, so that one side is 0 and the other side is 1, so that it can transmit and accept 2 values (1 bit) of information at the same time. Because the most simple keying phase shift method has strong noise resistance but poor transmission efficiency, QPSK with four phases and 8PSK with eight phases are often used.
