WebThe BPSK signal has two phases: 0 and π. The probability of a bit error in an AWGN channel is P b = Q ( 2 E b N 0), where N0 is the noise power spectral density. QPSK In quadrature phase shift keying, the message bits are grouped into 2-bit symbols, which are transmitted as one of four phases of a constant amplitude baseband signal.
