Method and apparatus for improving received signal quality in an impluse radio system

摘要

An impulse radio system includes an impulse transmitter that transmits a pulse train comprising a number of pulses that are positioned in time for conveying an information signal. An impulse receiver receives the pulse train in accordance with specified arrival times of each pulse and measures interference samples at interference sample times that do not coincide with the pulse arrival times. The interference sample times are varied and the received pulse train signal is modified until a received signal quality criterion is satisfied. The interference sample times may be specified by a code that may also specify pulse arrival times.
