Abstract
A timing recovery device for receiver installations using oversampling and adaptive equalization in association with differentially coherent demodulation, applicable in particular to receivers operating in diversity mode, derives a transition coding signal from the output signal of the adaptive equalizer. Channel estimator circuits receive this coding signal and digital signals supplied by oversampling devices on the diversity channels. The timing error is calculated from signals supplied by the estimators. The error calculation circuit controls an oscillator which generates a clock signal corresponding to the recovered symbol timing rate.
