Abstract

The present invention provides systems and methods for communication between ultra-wideband (UWB) devices. In general, the UWB device may characterize the attenuation, and other characteristics of the communication environment. Using these characteristics the UWB device can adapt various communication parameters to improve the communication quality. The UWB device may use these characteristics to establish zones and sectors for communication with other UWB devices. Based on this zone and sector assignment the UWB device may select communication parameters for communication with other UWB devices. 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.

Claims

1. A method of selecting at least one communication parameter in an ultra-wideband communication system based on a signal energy, the method comprising the steps of:

providing a first ultra-wideband device;

transmitting a message of a known energy from the first ultra-wideband device to a second ultra-wideband device;

receiving a response message from the second ultra-wideband device, the response message including a received energy of the known energy message; and

selecting at least one communication parameter based on the received energy of the known energy message.

2. The method of claim 1, wherein the communication parameter is selected from at least one of a group consisting of:

an ultra-wideband pulse modulation technique, a method of error detection, a method of error correction, a method of error control, a ultra-wideband pulse recurrence frequency, a data rate, a power of transmission, an ultra-wideband pulse shape, a configuration of a receiver, an ultra-wideband pulse width, a frame length, and a rate of time synchronization.

3. A computer program product for selecting at least one communication parameter in an ultra-wideband communication system based on a signal energy, the method comprising the steps of:

computer logic for transmitting a message of a known energy from a first ultra-wideband device to a second ultra-wideband device;

computer logic for receiving a response message from the second ultra-wideband device, the response message including a received energy of the known energy message; and

computer logic for selecting at least one communication parameter based on the received energy of the known energy message.

5. The computer program product of claim 3, wherein the computer program product is translated into a physical implementation.

6. A method of selecting at least one communication parameter in an ultra-wideband communication system based on a signal energy, the method comprising the steps of:

means for providing a first ultra-wideband device;

means for transmitting a message of a known energy from the first ultra-wideband device to a second ultra-wideband device;

means for receiving a response message from the second ultra-wideband device, the response message including a received energy of the known energy message; and

means for selecting at least one communication parameter based on the received energy of the known energy message.

7. The method of claim 6, wherein the communication parameter is selected from at least one of a group consisting of:
