Ultra-wideband communication apparatus and methods
First Claim
1. An ultra-wideband communication method, the method comprising the steps of:
- generating a communication frame comprising a synchronization section, and at least two data sections and at least two preamble sections;
transmitting the communication frame;
synchronizing a receiver with a transmitter using at least the synchronization section; and
re-synchronizing the receiver with the transmitter using at least one preamble section;
where the synchronization section and the preamble section both include a code, with the synchronization section comprising multiple copies of the code, followed by an inverse of the code.

Abstract
Apparatus and methods of ultra-wideband communication are provided. In one embodiment, a communication frame is generated and includes a synchronization section, and at least two data sections and at least two preamble sections. An ultra-wideband receiver synchronizes with the ultra-wideband transmitter using the synchronization section, and may also re-synchronize with the transmitter using at least one preamble section. In another embodiment, the length of the data sections are selected to ensure that drift between the ultra-wideband receiver and transmitter will be minimal before re-synchronization. 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.
