Abstract: Disclosed is an apparatus and method for low complexity, phase independent reception of FSK signals. A finite series of delay elements produces a plurality of equidistant samples of a received FSK signal. The plurality of equidistant samples is processed by an arithmetic unit using a phase independent algorithm to obtain an estimate of the received signal. The estimate of the received signal is then compared to a threshold value to determine if the estimate corresponds to a binary 1 or binary 0, which increments a counter corresponding to each binary value. Multiple estimates are counted over a baud interval of the received FSK signal and a binary 1 or binary 0 is output as a received data signal value depending upon which binary value the counter having the higher value corresponds to.
