4.4 Quadrature phase shift keying (QPSK) Quadrature phase shift keying (QPSK) has twice the bandwidth efficiency of BPSK since two bits are transmitted in a single modulation symbol. In the phase of the carrier takes on one of four equally spaced values‚ such as 0‚ π/2‚π and 3π/2‚ where each value of phase corresponds to a unique pair of message bits. The Quadrature phase shift keying (QPSK) signal for this set of symbol states may be defined as s_QPSK (t) =√(〖2E〗_s/T_s ) cos[〖2πf〗_c t +(i-1)π/2]
