Abstract:
1. A method of reducing potential interference in an impulse radio receiver, comprising the steps of: (a) receiving a signal including an impulse signal, the impulse signal including a sequence of impulses spaced in time from one another; (b) sampling the sequence of impulses at a sequence of data sample times to produce a sequence of data samples; (c) sampling the received signal at a time offset from each of the data sample times to produce a milling sample corresponding to each of the data samples, thereby producing a sequence of nulling samples corresponding to the time offset; (d) separately combining each of the data samples with a corresponding nulling sample from the sequence of nulling samples to produce a sequence of adjusted samples corresponding to the time offset; (e) determining a first quality metric associated with the sequence of adjusted samples; (f) determining a second quality metric associated with the sequence of data samples; and (g) selecting a preferred sequence of samples based on the first and second quality metrics.
