ABSTRACT:
Apparatus and methods of ultra-wideband (UWB) communication are provided. In one embodiment, an ultra-wideband receiver receives a serial data stream comprising a plurality of ultra-wideband pulses. A serial to parallel converter then converts the serial data stream into a plurality of parallel data streams, which are then matched. A combiner then combines the data streams, which are then fed to an equalizer that includes a hard decision element, a past decision element and a future decision element. 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.
