Method and apparatus for non-linear decision-feedback equalization in the presence of asymmetric channel |
摘要 |
Methods and apparatus are provided for determining the threshold position of one or more latches employed for decision-feedback equalization in the presence of a non-linear channel. A latch employed by a decision-feedback equalizer is positioned by constraining input data such that the input data only contains transitions from a first binary value; obtaining a plurality of samples of a single-sided data eye associated with the constrained input data; determining a threshold position of the latch based on the samples; and transforming the determined position to address the non-linearity of the channel. For example, a non-linear mapping table can map measured threshold values to transformed threshold values based on distance.
