摘要
The present invention time-relates to a method of compensating for burst-system group delay equalization interval and a pilot part and device. The weighted mean arrival time and determines the delay offset of the partial interval equalizer 350. Weighted mean arrival time is determined by using arrival times and the path of energy from the rake receiver 604. The difference between the weighted mean arrival time and a current delay offset is set to the difference X, the difference between these equalizer tap spacing 608 units. If the difference X is less than 1 or -1, current delay offset incremental delay offset 610, 612, 614, 616 as being of the equalizer filter tap coefficient updating interval number 618, Thieves are putting as much as 620. If not, does the current delay offset is not part interval equalizer filter coefficients is also not without shifting of the update (350). Adaptation and updating of the offset delay of the equalizer filter coefficients takes place only during the pilot burst to minimize adaptation transients.
