  • OBJECT AND MOVEMENT DETECTION
    Publication number: 20110096954
    Abstract: Motions, positions or configurations off, for example a human hand can be recognised by transmitting a plurality of transmit signals in respective time frames; receiving a plurality of receive signals; determining a plurality of channel impulse responses using the transmit and receive signals; defining a matrix of impulse responses, with impulse responses for adjacent time frames adjacent each other; and analysing the matrix for patterns (22) corresponding to the motion position or configuration.

  • CHANNEL IMPULSE RESPONSE ESTIMATION
    Publication number: 20100296368
    Abstract: A method of estimating the impulse response of a channel is disclosed. The method includes transmitting an impulse signal to the channel, detecting a received signal from the channel at a receiver, and calculating an estimate of the impulse response of the channel by applying a calculated inverse matrix of the impulse signal to the received signal.
