| 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.
