WebThe simplest BPSK scheme uses two phases to represent the two binary digits and is known as binary phase-shift keying. The resulting transmitted single for one bit time is. S (t) =A* cos (2*pi*fc*t) for binary 1. S (t) =A … WebThis general formula will work for DBPSK or DQPSK (since BPSK signals are real, the conjugate just drops out). The resulting signal stream S i lies on the same constellation as the input, so you can make hard decisions using the same rules you would for normal BPSK or QPSK.

"BPSK (also sometimes called PRK, phase reversal keying, or 2PSK) is the simplest form of phase shift keying (PSK). It uses two phases which are separated by 180° and so can also be termed 2-PSK. It does not particularly matter exactly where the constellation points are positioned, and in this figure they are shown on the real axis, at 0° and 180°. Therefore, it handles the high… " - Bpsk qpsk
