Abstract
A method and an apparatus for achieving fast resynchronization of received signals in a time slice in DVB-T/H systems. When the clock drift is low, the location of the symbol window can be decided based on a previous time slice. When the clock drift is high and when there are large delay spreads, the location of the symbol window can be decided based on the detected scattered pilot positions. The placement of the symbol window can further be enhanced through processing of the received TPS bits.
