Abstract
Various embodiments of the present invention provide systems and methods for data processing. For example, a data processing circuit is disclosed that includes first and second data detectors and an error cancellation circuit. The first data detector is operable to perform a data detection process on a first signal derived from a data input to yield a detected output. The second data detector circuit is operable to perform a data detection process on a second signal derived from the data input to yield a second detected output. The error cancellation circuit is operable to combine a first error signal derived from the detected output with a second error signal derived from the second detected output to yield a feedback signal. The feedback signal is operable to modify the data input during a subsequent period.
