Channel coding and reduced-complexity detection for magnetic recording.
(1997)
As an application, a modified EEPR4 (MEEPR4) channel with a 3-candidate LVA is shown to exhibit a 2 dB LVA gain. In addition, an error detection code is designed to increase the minimum distance by more than 2 dB with a ...
Design of low-density parity-check codes for magnetic recording channels.
(2002)
A technique for designing low-density parity-check (LDPC) error correcting codes for use with the partial-response channels commonly used in magnetic recording is presented. This technique combines the well-known density ...
Low-density parity-check coding for high-density magnetic recording systems.
(2004)
Our strategy is to combine advanced signal processing techniques, the core of which is soft-decision iterative channel detection, with powerful low-density parity-check (LDPC) coding techniques.
PARALLEL SUBSPACE SUBCODES OF REED-SOLOMON CODES FOR MAGNETIC RECORDING CHANNELS
(2010)
Read channel architectures based on a single low-density parity-check (LDPC) code are being considered for the next generation of hard disk drives. However, LDPC-only solutions suffer from the error floor problem, which ...
Error-correction coding for high-density magnetic recording channels.
(2004)
Finally, a promising algorithm which combines RS decoding algorithm with LDPC decoding algorithm together is investigated, and a reduced-complexity modification has been proposed, which not only improves the decoding ...
