Ultra-wideband synchronization systems and methods
First Claim
1. A method of synchronization comprising the steps of:
- transmitting an ultra-wideband signal comprising a synchronization sequence from a first device having a first timing reference;
receiving the ultra-wideband signal at a second device having a second timing reference;
synchronizing the second timing reference to the first timing reference based on the time of receipt of the synchronization sequence; and
updating a statistics register on the second device with the time of arrival of the synchronization sequence.

Abstract
The present invention provides systems and methods for ultra-wideband communication devices to maintain synchronization. One embodiment of the present invention provides a method by which ultra-wideband communication devices may update their timing references by the use of a statistics register. In another embodiment, a network of ultra-wideband communication devices uses the statistics registers of a plurality of ultra-wideband devices to update their timing references based on calculating a function. 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.

10. A communication network, comprising:
-
a first device transmitting an ultra-wideband signal; and
at least two receiving devices receiving the ultra-wideband signal, with each of the at least two receiving devices transmitting a statistics register to the first device;
wherein the first device calculates a timing reference adjustment from the received statistics registers. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
