  • Multipass approach for performing channel equalization training
    Patent number: 8897352
    Abstract: A method comprises performing a first pass test over a plurality of sets of equalization coefficients to filter the plurality of sets of equalization coefficients to produce one or more filtered sets of equalization coefficients. Each filtered set of equalization coefficients meets a first predetermined threshold. The method also comprises performing a second pass test over the one or more filtered sets of equalization coefficients to determine a final set of equalization coefficients that meets a second predetermined threshold. The second pass test produces more accurate results than the first pass test.

  • ITERATIVELY SCANNING EQUALIZATION COEFFICIENTS TO OPTIMIZE SIGNAL QUALITY IN A DATA COMMUNICATION LINK
    Publication number: 20140307766
    Abstract: A method includes iteratively scanning, through a processor, at least a portion of a map of equalization coefficients related to channel equalization in a data communication link based on an ordinal integer step size S>1 for N (N>1) different sequences thereof to determine optimal points therein for which a signal quality in the data communication link is optimal. The method also includes performing, through the processor, a fine search for optimal equalization coefficients based on the determined optimal points.
