A common type of digital communication system is binary frequency shift keying FSK whereby every T seconds the transmitter sends a pulse of one of two frequencies. The receiver makes a decision every T seconds as to which frequency was transmitted. A sub-optimum receiver for this case obtains estimates of the two noise waveforms by passing received signals through filters centered at the sending frequencies and then crosscorrelates these estimates with the received waveform. Two slightly different versions of this cross-correlator were considered, and the probability of error for each case was calculated. The results seem to agree with previous experimental work by Cossette and Wolf.
