Abstract :
The striking benefits of iterative detection have generated strong interest in the disk drive signal processing area, but thus far application of this technology has been rather limited. We review the benefits that the most interesting iterative detectors have over the industry-standard partial-response maximum-likelihood (PRML) detectors, and examine the hardware complexity issues that have so far stood in the way of practical implementations.
