Abstract
Various approaches to recover data are described. An one example, an encoded data stream is processed in a first channel decoder producing a channel decoder output. The channel decoder output and the encoded data stream are processed in an error compensation unit to compensate the channel decoder output for low frequency noise and produce an error compensated data stream. The error compensated data stream is processed in a second channel decoder to produce a recovered data stream, wherein the recovered data stream has a reduction in the number of errors as compared to the encoded data stream. Systems to iteratively recover data from an encoded data stream are also described.
