Patent ID: 8737459

Claim:
A method for optimizing transmitter equalization settings, comprising: selecting an initial point on a two-dimensional search grid wherein each point on the search grid is associated with a first equalizer setting and a second equalizer setting and is addressable using at least a two-dimensional coordinate system; determining an initial eye margin of an initial data signal that is equalized in accordance with the first equalizer setting and the second equalizer setting that are associated with the initial point and that is transmitted across a channel medium; selecting adjacent points that are adjacent to the initial point; determining an eye margin for each data signal equalized in accordance with the first equalizer setting and the second equalizer setting that are associated with each selected adjacent point to the initial point and that are transmitted across the channel medium; and comparing each of the determined eye margins to determine when the eye margin is higher than the initial eye margin, and when the eye margin is higher than the initial eye margin, using coordinates of the point associated with the eye margin which is higher than the initial eye margin to select an optimized first equalizer setting and an optimized equalizer setting for subsequent transmissions of data signals; wherein the selecting adjacent points that are adjacent to the initial point includes selecting nearest neighbors having a distance of one as defined by the formula: dist=| x|+|y| where “dist” is the distance, “x” is an integer coordinate in a first direction for each of the selected adjacent points, and “y” is an integer coordinate in a second direction for each of the selected adjacent points.
