ABSTRACT:
A method for maintaining synchronization between a transmitter and a receiver is disclosed. The method offsets time drift which causes a degradation in the quality of communication between a transmitter and a receiver. The method comprises using a first sampling time to obtain a first sequence of hard decision symbols for decoding contents of a portion of a received packet, switching to a second sampling time upon degradation in a reliability of the symbols, and using the second sampling time to obtain a second sequence of hard decision symbols for decoding contents of a remaining portion of the received packet.
