Abstract
An ultra-wideband communication and/or location system having a plurality of channels, each implementing a respective one of a plurality of predetermined codewords. Within each channel, one or more predetermined pulse repetition frequencies are defined. Within a single UWB system, more than two networks of transceivers may be co-located without mutual interference if each is assigned a unique combination of codewords and spreading factors.
Claims3
A method in an ultra-wideband (“UWB”) communication and/or location system comprising co-located first and second UWB networks, the first UWB network comprising a first UWB transmitter and a first UWB receiver, the second UWB network comprising the first UWB transmitter and a second UWB receiver, the method comprising the steps of:
- [1] selecting a first and a second unique preamble code (“pCode)”, each pCode comprising a combination of:
- a selected one of a plurality of predefined modulation codes;
- and
- a selected one of a plurality of spreading factors;
- wherein the combination results in a unique symbol length for each pCode;
- [2] assigning to each of said first and second UWB networks, respectively, the first and second pCodes;
- [3] simultaneously operating each of said first and second UWB networks, respectively, using the first and second pCodes;
- and
- [4] simultaneously switching each of the first and second UWB networks to a different one of the first and second unique pCodes in accordance with a precoordinated preamble schedule (“pSchedule”).
A UWB communication system comprising a co-located first and second UWB networks, the first UWB network comprising a first UWB transmitter and a first UWB receiver, the second UWB network comprising the first UWB transmitter and a second UWB receiver, said UWB communication system being configured to perform a method comprising the steps of:
- [1] selecting a first and a second unique preamble code (“pCode)”, each pCode comprising a combination of:
- a selected one of a plurality of predefined modulation codes;
- and
- a selected one of a plurality of spreading factors;
- wherein the combination results in a unique symbol length for each pCode;
- [2] assigning to each of said first and second UWB networks, respectively, the first and second pCodes;
- [3] simultaneously operating each of said first and second UWB networks, respectively, using the first and second pCodes;
- and
- [4] simultaneously switching each of the first and second UWB networks to a different one of the first and second unique pCodes in accordance with a precoordinated preamble schedule (“pSchedule”).
