Systems and methods for hybrid algorithm gain adaptation
Various embodiments of the present invention provide systems and methods for data processing. For example, some embodiments of the present invention provide data processing circuits that include a variable gain amplifier, a gain circuit, and hybrid gain feedback combination circuit. The variable gain amplifier is operable to apply a gain to a data input corresponding to a gain feedback value and providing an amplified output. The gain circuit is operable to calculate a first algorithm error component and a second algorithm error component based at least in part on the amplified output. The hybrid gain feedback combination circuit is operable combine the first algorithm error component and the second algorithm error component to yield the gain feedback value when the data input includes a synchronization pattern.
