Abstract
In one embodiment, a computer program product for iterative read channel operation has program instructions embodied therewith that are executable by a controller to cause the controller to: in an iterative process until a maximum number of iterations has been reached or a valid codeword is produced: execute one or more digital front-end (DFE) functions on a plurality of signal samples employing the set of decisions provided by a decoder; execute a detection algorithm on the signal samples using a detector employing the set of decisions provided by the decoder to regenerate the set of decisions provided by a detector; execute a decoding algorithm of an error correcting code (ECC) using the set of decisions provided by the detector to regenerate the set of decisions provided by the decoder; and output decoding information relating to the signal samples when the decoding algorithm produces a valid codeword.
