    摘要： A method and apparatus for moderating interference with impulse radio wireless control of an appliance; the control is effected by a controller remote from the appliance transmitting impulse radio digital control signals to the appliance. The control signals have a transmission power and a data rate. The method comprises the steps of: (a) in no particular order: (1) establishing a maximum acceptable noise value for a parameter relating to interfering signals; (2) establishing a frequency range for measuring the interfering signals; (b) measuring the parameter for the interference signals within the frequency range; and (c) when the parameter exceeds the maximum acceptable noise value, effecting an alteration of transmission of the control signals. The apparatus is for moderating interference with impulse radio wireless control of an appliance; the control being effected by a controller remote from the appliance, the controller transmitting impulse radio digital control signals to the appliance; the control signals having a transmission power and a data rate; the apparatus comprising: a threshold unit for establishing a maximum acceptable noise value for a parameter relating to interfering signals in a predetermined frequency range; and a measuring unit for measuring the parameter for the interference signals within the frequency range; and a transmission control unit for effecting alteration of the transmission of the control signals when the parameter exceeds the maximum acceptable noise value.

    摘要： A system and a method for position determination by impulse radio using a first transceiver having a first clock providing a first reference signal and a second transceiver placed spaced from the first transceiver. The system determines the position of the second transceiver. The second transceiver has a second clock that provides a second reference signal. A first sequence of pulses are transmitted from the first transceiver. The first sequence of pulses are then received at the second transceiver and the second transceiver is then synchronized with the first sequence of pulses. A second sequence of pulses are transmitted from the second transceiver. The first transceiver receives the second sequence of pulses and the first transceiver is synchronized with the second sequence of pulses. A delayed first reference signal is generated in response to the synchronization with the second sequence of pulses. A time difference between the delayed first reference signal and the first reference signal is then measured. The time difference indicates a total time of flight of the first and second sequence of pulses. The distance between the first and the second transceiver is determined from the time difference. The direction of the second transceiver from the first transceiver is determined using a directional antenna. Finally, the position of the second transceiver is determined using the distance and the direction.
