Applications of iterative decoding to magnetic recording channels.
(2002)Finally, Q-ary LDPC (Q-LDPC) codes are considered for MRCs. Belief propagation decoding for binary LDPC codes is extended to Q-LDPC codes and a reduced-complexity decoding algorithm for Q-LDPC codes is developed. Q-LDPC ... -
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 ... -
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 ... -
Iterative decoding for magnetic recording channels.
(2000)The success of turbo codes indicates that performance close to the Shannon limit may be achieved by iterative decoding. This has in turn stimulated interest in the performance of iterative detection for partial-response ... -
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.
