Abstract

Apparatus and methods of ultra-wideband communication are provided. In one embodiment, an ultra-wideband receiver comprises an envelope detector that detects the amplitude of a received ultra-wideband signal and generates a waveform representative of the envelope of the received ultra wideband signal A sign detector then determines a sign associated with a data bit encoded on the received ultra-wideband signal. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.
