| 1. A method of generating an ultra wideband signal, comprising:
generating an information signal comprising a plurality of different data states; and
generating one of a plurality of different ultra wideband waveforms in accordance with a corresponding one of said plurality
of different data states of the information signal, said plurality of different ultra wideband waveforms including a first
ultra wideband waveform that is an impulse waveform and said plurality of different ultra wideband waveforms including a second
ultra wideband waveform that is an inverse of the first ultra wideband waveform;
wherein only one of said plurality of different ultra wideband waveforms is generated based upon any one of said plurality
of different data states of the information signal.
