ABSTRACT:
In a receiver of the type that receives an incoming phase shift keying (PSK) signal and recovers data therefrom, a data recovery circuit which utilizes convolution techniques. The data recovery circuit generates an array of phase vectors representative of the incoming PSK signal and convolutes the vectors against a weighting curve to generate binary weighted outputs. The magnitude of the outputs represents one of the phases of the incoming PSK signal. If the incoming phase is undefined, the binary weighted outputs are not updated.
