An optical pulse sequence derived from a single pulse can be summed coherently by a delay network provided that delay lengths are strictly controlled. We demonstrate coherent correlation experimentally, using an electronic feedback circuit to interferometrically stabilize fiber delay lengths. The potential for application to code-division multiple access (CDMA) networks is demonstrated by using coherent correlation to distinguish a data sequence from an incoherent back-ground signal
