Abstract:
In a receive system, a plurality of correlators correlate a received signal with a plurality of delayed versions of a reference signal to generate a plurality of correlator outputs. A timing error detector estimates an optimal timing based on a set of correlator outputs, and determines a timing error based on (i) the estimated optimal correlation point and (ii) an existing timing, such that the timing error is hard or soft limited between two positive thresholds and two negative thresholds.
