Time estimation for gsm - bursts on the basis of previously determined average values

摘要

There is disclosed 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 estimating the timing position of the data bursts received in the data stream. For each of the first N received data bursts, the receiver estimates a plurality of timing locations of the training sequence, correlates the training sequence for each estimated timing location, and determines the timing location associated with the highest correlation value. The receiver then determines the average timing location of the highest correlation values for each of the first N data bursts. For the next M data bursts the receiver estimates the timing location of each data burst based on the average timing location for the first N data bursts.
