Binary Phase shift keying (BPSK) is one of the basic modulation schemes in which the phase of the carrier signal is varied or switched according to the input message pulses. When the modulation input is at logic 1, a finite number of cycles of a sinusoidal signal are transmitted and when the input is at logic 0, phase of the sinusoid is changed. We have discussed in detail about binary phase
