Patent ID: 7418029

Claim:
A method for detecting an ultra wideband signal, comprising the steps of: a) receiving an ultra wideband signal; b) establishing, using a plurality of processing blocks, a plurality of time offsets between a transmitter clock and a receiver clock, said plurality of processing blocks controlling at least one scanning process, said plurality of time offsets corresponding to said at least one scanning process; c) comparing, using said plurality of processing blocks, a plurality of values of a parameter of the received ultra wideband signal to an acceptance criteria, each one of said plurality of values being in accordance with a corresponding one of said plurality of time offsets; and d) if each one of said plurality of values of said parameter fails to meet the acceptance criteria, returning to step (a), and if any one of said plurality of values of said parameter meets the acceptance criteria, locking on the received ultra wideband signal.
