Patents by Inventor Olivier Souloumiac

Olivier Souloumiac 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).

  • Patent number: 9106265
    Abstract: Data flow control in a television receiver controls the output of the frequency deinterleaver (FDI) and the time deinterleaver (TDI) to prioritize processing control information having transmission parameters needed for processing data, thereby facilitating use of one FEC decoder.
    Type: Grant

  • Patent number: 8644370
    Abstract: In one embodiment, a method can provide for dynamic updating of slope values used in determining a soft decision for a demodulated signal obtained in a receiver from a broadcast signal received by the receiver. The method includes generating a channel estimate for a channel traversed by the signal, computing channel state information from the channel estimate, computing statistical information from the channel state information, determining a slope value based at least in part on the statistical information, calculating a log-likelihood ratio (LLR) value for the signal, and applying the slope value to the LLR value to obtain a weighted LLR value.

    Inventors: Emmanuel Gautier, Olivier Souloumiac
  • Patent number: 8555131
    Abstract: A method for controlling power consumption of an iterative decoder based on one or more criteria is described. The method may include progressively enabling and disabling nodes of the iterative decoder to perform iterative decoding on a demodulated signal to provide a decoded signal with minimal variation of a supply voltage.

  • Patent number: 8433970
    Abstract: A method for controlling power consumption of an iterative decoder based on one or more criteria is described. The method may include performing iterative decoding on a demodulated signal to provide a decoded signal, receiving information regarding the iterative decoding, and based on the information controlling a number of nodes of the iterative decoder to enable during a next iteration of the iterative decoding.

  • Patent number: 8341486
    Abstract: A method for controlling power consumption of an iterative decoder based on one or more criteria is described. The method may include performing iterative decoding on a demodulated signal to provide a decoded signal, determining whether the iterative decoding is suffering an impairment, and terminating the iterative decoding responsive to the determination of the impairment, otherwise continuing the iterative decoding to provide the decoded signal.

  • Patent number: 8237869
    Abstract: A multi-standard single-chip receiver for digital demodulation of TV signals broadcasted over any of multiple digital television means, e.g., satellite, cable and terrestrial, is provided. The receiver can receive and demodulate a variety of different signal types received from one or more up-front tuners. A demodulator architecture in accordance with an embodiment of the present invention can be optimized to re-use common demodulation processing blocks for the different incoming signal types.
