Abstract:
Various embodiments are disclosed for providing timing tracking loops in a communication system. A communication system includes a delay locked loop (DLL) comprising a maximum region detector configured to identify a target channel profile comprising at least a portion of the multipath signals based on the timing information, the maximum region detector further configured to apply a weight vector to each channel tap in the target channel profile and determine a tap with a maximum power level relative to remaining channel taps in the channel profile. The system further comprises a window timing loop (WTL) adjuster configured to track a position of a channel estimation window (CEW) within an observation window corresponding to the maximum channel energy level, where the maximum channel energy level corresponds to the sum of the energy of all the taps for a given window.
