  • Patent number: 8483720
    Abstract: A system and method is provided for processing communication signals in a wireless personal area network (WPAN) using a transceiver comprising a first transmitter and a first receiver operable to transmit and receive signals using a first transmission protocol and a second transmitter operable to transmit signals using a second transmission protocol. In various embodiments, the first receiver is used to receive a first signal that was transmitted using the first communication protocol and the second transmitter is used to transmit a second signal using the second transmission protocol in response to receipt of the first signal. The second signal is then processed to determine the location of the object. In some embodiments, the first transmission protocol is compliant with an Institute of Electrical and Electronics Engineers 802.15.4 transmission protocol and the second transmission protocol is compliant with an Ultra-Wide Band (UWB) protocol.

  • Publication number: 20070033000
    Abstract: A non-iterative frequency domain method for the accurate and efficient simulation of nonlinear systems is presented. In one aspect of the present invention, simulating a nonlinear system is accomplished by first modeling the system and generating parameters that describe the nonlinear system. The system is represented in the frequency domain as an inverse convolution equation (ICE), comprising cascaded convolutions and frequency representations of known and unknown signals. Next, the order of the ICE is determined based upon the degree of nonlinearity in the system. Finally, a general ICE solver algorithm is adapted to the ICE order of the frequency model, and the specific ICE solver algorithm is applied to in order to solve for an unknown signal. In another aspect of the invention, the non-iterative method for simulating nonlinear systems is combined with cross-referenced coordinate (CRC) techniques in order to increase the computational efficiency of the simulation.
