Abstract:
1. A data processing system, the data processing system comprising: a data detector circuit operable to apply a data detection algorithm to a data input to yield a first detected output; a data decoder circuit operable to apply a data decoding algorithm to a decoder input to yield a decoded output, wherein the decoder input is derived from the first detected output; a potential trapping set detection circuit operable to identify a potential trapping set based at least in part on the decoded output; an unreliable location identification circuit operable to identify an unreliable location in the data input using a combination of the data input and a filtered version of the data input; a data instance modification circuit operable to: wherein the data detector circuit is further operable to apply the data detection algorithm to the detector input to yield a second detected output.
