Ultra-wideband communication apparatus and methods
First Claim
1. An ultra-wideband communication method, the method comprising the steps of:
- transmitting a serial data stream comprising a plurality of ultra-wideband pulses;
receiving the serial data stream;
splitting the serial data stream into a plurality of parallel data streams;
shifting a phase of at least one of the plurality of parallel data streams;
combining the plurality of parallel data streams into a combined data stream; and
equalizing the combined data stream.

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.

11. An ultra-wideband receiver, comprising:
-
a receiver structured to receive a serial data stream comprising a plurality of ultra-wideband pulses;
a serial to parallel converter configured to receive the serial data stream and convert it into a plurality of parallel data streams;
a plurality of matched filters communicating with the serial to parallel converter, the plurality of matched filters configured to match each of the parallel data streams;
a combiner configured to combine the matched parallel data streams; and
an equalizer comprising;
a hard decision element configured to generate a hard decision estimate of an input sample;
a past decision element configured to multiply at least one past decision estimate with an associated coefficient; and
a future decision element configured to multiply at least one future decision estimate with an associated coefficient. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
