(However in most wireless applications, the BPSK signal would not have a rectangular pulse but be pulse shaped such as with root-raise cosine pulse shaping in the transmitter, and we would then weight the received samples with another root-raised cosine impulse response in the integration for optimum matched filtering). If the receiver is not synchronized with the transmitter, the starting and ending of a symbol at the receiver will be different than the transmitter, which will lead to errors. Phase-shift keying (PSK) is a digital modulation process which conveys data by changing (modulating) the phase of a constant frequency reference signal (the carrier wave).The modulation is accomplished by varying the sine and cosine inputs at a precise time.
