Systems and methods for floating variance branch metric calculation

摘要

The present inventions are related to systems and methods for data processing, and more particularly to systems and methods for data detection. As one example, a data processing system is described that includes a variance calculation circuit operable to calculate a variance of a data input; and a branch metric calculation circuit operable to calculate a branch metric based at least in part on the variance.
