Abstract
Embodiments are related to systems and methods for data processing, and more particularly to systems and methods for multi-dimensional signal equalization. In one case, a data processing system is discussed that includes: a first equalizer governed at least in part by a first coefficient; a second equalizer circuit governed at least in part by a second coefficient; and a constraint circuit operable to force a sum of at least the first coefficient and the second coefficient to equal a defined value.

A data processing system, the system comprising:
- a first equalizer circuit, wherein operation of the first equalizer circuit is governed at least in part by a first coefficient;
- a second equalizer circuit, wherein operation of the second equalizer circuit is governed at least in part by a second coefficient;
- and
- a constraint circuit operable to force a sum of at least the first coefficient and the second coefficient to equal a defined value.
A method for data processing, the method comprising:
- modifying a first coefficient value, a second coefficient value, a third coefficient value, and a fourth coefficient value based upon a feedback value;
- constraining the first coefficient value and the second coefficient value such that a sum of at least the first coefficient value and the second coefficient value equals a defined value;
- applying a first equalization algorithm by a first equalizer circuit guided by at least the first coefficient value and the third coefficient value to yield a first equalized output;
- applying a second equalization algorithm by a second equalizer circuit guided by at least the second coefficient value and the fourth coefficient value to yield a second equalized output, wherein the second coefficient value and the fourth coefficient value are only used by the second equalizer circuit;
- and
- combining the first equalized output and the second equalized output to yield a common equalized output.
A data processing system, the system comprising:
- a first means for equalizing data using at least a first coefficient;
- a second means for equalizing data using at least a second coefficient, wherein the second coefficient is only used by the second means for equalizing;
- and
- a means for constraining the first coefficient and the second coefficient such that a sum of the first coefficient and the second coefficient equals a constant.
