Abstract
A receiver for recovering digital data from a phase-shift modulated carrier in a data communications system employs a matched filter within the servo loop controlling the local oscillator frequency to increase the signal to noise ratio of the receiver. Thus signals having an amplitude less than the amplitude of harmonics of the carrier can be detected. In the preferred embodiment, the matched filter comprises an integrate and dump filter which integrates at the received data baud rate. ,
