VELOCITY RESPONSIVE TIME TRACKING |
摘要 |
The velocity of a wireless communications device (WCD) is estimated. In response to this estimated velocity, a tracking speed of a filter is determined that corresponds to the estimated velocity. The filter filters a timing error signal to produce a control signal that controls the timing of a synchronization clock. This synchronization clock may be a finger clock that controls the timing of a pseudonoise (PN) sequence generator configured for despreading a pilot symbol sequence.
