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
selecting at least one of the plurality of data streams for communication.

Abstract
Apparatus and methods of ultra-wideband (UWB) communication are provided. In one embodiment, an UWB communication system transmits a serial data stream comprising a plurality of ultra-wideband pulses. These UWB pulses are received at a receiver that splits the serial data stream into a plurality of parallel data streams. The phase of at least one of the plurality of parallel data streams is then shifted, and then the plurality of parallel data streams are combined into a combined data stream. 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.
