ABSTRACT:
A technique is described for determining the timing of a received signal that includes one or more time-delayed versions of a reference signal traveling over respective different signal paths. The technique includes correlating the received signal with the reference signal to produce a correlated signal; determining whether the correlated signal includes a signal peak that corresponds to the direct path of the received signal; and iterative repeating these operations until a signal peak is determined to correspond to the direct path of the received signal. In each successive iteration, the reference signal corresponding to at least the greatest signal peak in the correlated signal is regenerated, and contributions from each regenerated reference signal are removed from the received signal prior to correlating the received signal in the next iteration.
