    摘要: Various embodiments of the present invention provide systems and methods for data processing. For example, a data processing system is disclosed that includes a combination data decoder circuit. The combination data decoder circuit includes a first decoder circuit and a second decoder circuit. The first decoder circuit is operable to apply a first data decode algorithm to a decoder input to yield a decoded output. The second decoder circuit is operable to apply a second data decode algorithm to a subset of the decoded output to modify at least one element of the decoded output to yield a modified decoded output.

    摘要: Various embodiments of the present invention provide systems and methods for data processing. As an example, a data processing system is discussed that includes: a data detector circuit, a symbol selective scaling circuit, and a data decoder circuit. The data detector circuit is operable to apply a data detection algorithm to a data input guided by a first data set derived from a decoded output to yield a detected output. The symbol selective scaling circuit is operable to selectively scale one or more symbols of a second data set derived from the detected output to yield a scaled data set. The data decoder circuit operable to apply a data decode algorithm to a third data set derived from the scaled data set to yield the decoded output.
