Rank-order equalization

摘要

For digital data transmitted using a vector signaling encoding, a rank-order equalizer cancels various channel noise such as inter-symbol interference. Further, rank-order units may be cascaded to achieve improved equalization over successive sample vector signals in a rank-order equalizer. Multiple rank-order equalizers further operate in parallel in a feed forward mode or in series in a feedback mode to provide a continuous vector signaling stream equalization.

1. A method for equalizing signals transmitted over a communication bus comprising n wires, the method comprising:
generating two sets of samples at two distinct time instances; determining the rank order of the first set of samples; using the result of the rank order to generate a set of coefficients; and subtracting the set of coefficients from the second set of samples.
