  • Systems and methods for determining non-linear precoding coefficients
    Patent number: 9800720
    Abstract: Systems and methods for determining non-linear precoding coefficients are disclosed. In some embodiments, a method of determining non-linear precoding coefficients for transmitting at least one frequency tone on lines includes obtaining a channel matrix that relates an input of the lines to an output of the lines for the at least one frequency tone. The method also includes computing a metric for each line in a subset of the lines and determining a line order for the subset of the lines based on the metric for each line in the subset of the lines. The method also includes reordering elements of the channel matrix based on the line order for the subset of the lines to create a reordered channel matrix and determining the non-linear precoding coefficients based on the reordered channel matrix. This may provide a systematic way to sort lines and balance the bit rates between different lines.
