Abstract
Various embodiments of the present invention provide systems and methods for data processing. For example, a data processing circuit is discussed that includes a data detector circuit, a detector mimicking circuit, and an error calculation circuit. The data detector circuit is operable to perform a data detection process on a first signal derived from a data input to yield a detected output. The data mimicking circuit is operable to process a second signal derived from the data input to yield a mimicked output. The error calculation circuit is operable to calculate a difference between the second signal and a third signal derived from the mimicked output to yield a feedback signal. The feedback signal is operable to modify the data input during a subsequent period.
