1. A method for synchronizing a UWB receiver with an incoming UWB signal, comprising steps of:

  • receiving the incoming UWB signal;

    generating a receiver signal at the UWB receiver;

    analyzing the incoming UWB signal in light of the receiver signal to produce an analysis result;

    comparing a parameter of the analysis result with a predetermined threshold to produce a comparison result;

    shifting a phase of said receiver signal when said parameter of said analysis result is beyond said predetermined threshold;

    changing a value of said predetermined threshold; and

    repeating said steps of comparing and shifting using the changed predetermined threshold.
