Patent ID: 7756230

Claim:
A method for synchronizing on a pulsed waveform sequence including at least one pulsed waveform, the method comprising the steps of: (a) providing an impulse radio receiver including a radio frequency (RF) front end, said RF front end operatively connected to a demodulator, said demodulator operatively connected to a processing unit; and (b) powering at least a portion of at least one RF component selected from a group consisting of said RF front end and said demodulator, solely during at least one time window sufficient for testing at least one hypothesis regarding timing of the at least one pulsed waveform; wherein said powering is controlled by said processing unit; and (c) scanning for and thereby acquiring the pulsed waveform sequence by said processing unit, wherein said acquiring is achieved with a non-negligible probability of a false alarm; wherein said plurality of hypotheses are tested in parallel, whereby performance of said processing unit is maintained despite the non-negligible probability of a false alarm.
