Tactical winning device for reception system with adaptive deconstruction by means of over-scanning together with differential coherent demodulation

摘要

The present invention relates to a clock recovery circuit for a receiving unit with auto-adaptive equalisation using oversampling together with differentially coherent demodulation. It applies in particular to receivers operating in diversity mode. …??The clock recovery circuit comprises a means (15) which derives a transition-coding signal from the signal output by the auto-adaptive equaliser, channel estimator circuits (23) which receive this coding signal and the digital signals provided by the oversampling circuits (2) placed on the diversity paths, a device (25) for computing the clock error from signals provided by the estimators, the error computing device (25) controlling an oscillator (29) which generates the timing signal corresponding to the symbolic clock recovered. …IMAGE…
