Patent ID: 7177376

Claim:
A receiver for determining a synch time for recovering data from signal samples, said signal samples including a portion corresponding to a guard period which carries data repeated from a data bearing portion of said signal samples, said receiver comprising: a pilot assisted tracker operable to determine an adjustment to said synch time from a pilot assisted channel impulse response estimate, a guard adapted matched filter processor comprising a filter and a filter controller operable to set the impulse response of said filter to the signal samples from said guard period, to excite said filter with said signal samples to generate an output signal which provides a further representation of said channel impulse response, and to generate an adjustment to said synch time from said further representation of said channel impulse response, and a synch timing adjustment estimator operable to adjust said synch time in accordance with the adjustment provided by at least one of said pilot assisted tracker and said guard adapted matched filter processor.
