ABSTRACT:
A method and apparatus for estimating the timing position of data bursts received in a data stream, where each data burst includes a number of bits comprising a training sequence in a fixed location. The receiver includes circuitry for, in respect of each received data burst, estimating at least one position of the timing location of the training sequence, equalizing the data burst for each estimated position, and correlating each equalized data burst. Where a plurality of positions of the timing location of the training sequence are estimated, the receiver circuitry, for each received data burst, determines the correlation result having the highest value and retains the equalized data burst associated with the correlation result having the highest value.
