ABSTRACT:
An apparatus and method for enhancing the signal-to-noise ratio of an input signal which divides the input signal into a plurality of divided signals of equal power, introduces a delay into a corresponding one of the plurality of divided signals, mixes together pairs of the plurality of delayed divided signals, and sums the mixed signals. The apparatus and method of the present invention may be employed in a signal detector to improve the sensitivity of the signal detector.
