Patent ID: 7079604

Claim:
A method for identifying a phase of an incoming ultrawide bandwidth (UWB) signal at a UWB receiver, comprising the steps of: receiving incoming pulses of the incoming UWB signal, adjacent pulses of said incoming pulses arriving at a predetermined interval; generating first local pulses at a first detecting arm in the UWB receiver; generating second local pulses at a second detecting arm in the UWB receiver; correlating the first and second local pulses with the incoming pulses to produce first and second correlation functions, respectively; selecting one of the first and second detecting arms to identify the phase based on the first and second correlation functions, and to demodulate data from the incoming UWB signal; and selecting another of the first and second detecting arms to vary its operational phase and continue to correlate the first or second local pulses with the incoming pulses to refine the phase.
