  • Precoder construction and equalization
    Patent number: 8681849
    Abstract: Apparatus and methods are provided to construct parameters associated with a precoder to a channel. Embodiments include apparatus and methods to apply a maximum a posteriori probability (MAP) equalization using offsets of signals introduced at a transmit end of a channel. Embodiments include apparatus and methods to construct a channel precoder based on using approximation of channel responses for a range of channel lengths.
    Type: Grant
    Filed: June 29, 2005
    Date of Patent: March 25, 2014
    Assignee: Intel Corporation
    Inventors: Felix Aleksandrovich Taubin, Sergey Valentinovich Bulatnov
  • Precoder design for different channel lengths
    Patent number: 8036305
    Abstract: Apparatus and methods construct parameters for a unit associated with a precoder to a channel. Embodiments include forming a plurality of values for precoder constructions, where the values may be obtained from applying a transmission quality criterion to each precoder construction for varying channels lengths. Each precoder construction may be built for a predetermined channel length with a different channel length for each precoder construction. A subset of the precoder constructions operate substantially over the entire distance range covered by the varying channels lengths.

  • Autoregressive Moving Average Modeling for Feedforward and Feedback Tomlinson-Harashima Precoder Filters
    Publication number: 20090219984
    Abstract: Apparatus and methods provide a Tomlinson-Harashima precoder scheme in which a feedback filter may be constructed to match an approximated feedforward filter, where the feedforward filter is approximated using autoregressive moving average modeling.
