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 ...
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 ...
