WebIn the quadrature phase-shift keying (QPSK) scheme, two bits are grouped at a time, and mapped into one of the four possible signals. As with BPSK (, the information in QPSK () is contained in the carrier phase (i.e., the phase of the carrier takes on one of four equally-spaced values). The QPSK signal set can thus be analytically described as:
