  • Method and system for unconstrained frequency domain adaptive filtering
    Patent number: 8984038
    Abstract: Aspects of a method and system for unconstrained frequency domain adaptive filtering include one or more circuits that are operable to select one or more time domain coefficients in a current filter partition. A value may be computed for each of the selected one or more time domain coefficients based on a corresponding plurality of frequency domain coefficients. The corresponding plurality of frequency domain coefficients may be adjusted based on the computed values. A subsequent plurality of frequency domain coefficients in a subsequent filter partition may be adjusted based on the computed values. Input signals may be processed in the current filter partition based on the adjusted corresponding plurality of frequency domain coefficients. A time-adjusted version of the input signals may be processed in a subsequent filter partition based on the adjusted subsequent plurality of frequency domain coefficients.
    Type: Grant

    Date of Patent: March 17, 2015
    Assignee: Broadcom Corporation
    Inventors: Kuoruey (Ray) Han, Peiqing Wang, Linghsiao Wang, Kishore Kota, Arash Farhoodfar
