Patents by Inventor Robert Jan Piechocki

Robert Jan Piechocki has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Communication system, method and apparatus
    Patent number: 8879664
    Abstract: Encoding of a message is conducted using codewords selected from a codebook. The selected codewords are used to construct a corresponding plurality of waveforms, which are then weighted and added to form a signal for transmission. At a receiver, channel impulse response is used to determine which codewords from the known codebook have been used, and by which weights from a known constellation of weights the resultant waveforms have been weighted. A message embedded in a received signal can then be detected.
    Type: Grant
    Filed: August 29, 2012
    Date of Patent: November 4, 2014
    Assignee: The University of Bristol
    Inventors: Robert Jan Piechocki, Dino Sejdinovic

  • SIGNAL DECODING METHODS AND APPARATUS
    Publication number: 20080292016
    Abstract: This invention is generally concerned with methods, apparatus and processor control code for decoding a signal received over a MIMO (multiple input-multiple output) channel.

  • Apparatus and Method of Equalisation
    Publication number: 20080123727
    Abstract: To reduce the number of components needed when compared with an exact-calculation analog equalizer, an analog equalizer includes an iterative mechanism arranged in operation to generate an estimate of marginal posterior expectations for received bit values.

  • Signal decoding methods and apparatus
    Publication number: 20040081074
    Abstract: This invention generally relates to apparatus, methods and computer program code for decoding a received signal where the signal is received by a received antenna from a plurality of transmit antennas. The invention addresses the further difficulties which arise when only limited or known information for deriving an estimate of the responses of the channels between the transmit antennas and the receive antenna is available.
