  Abstract

When we apply the LDPC code for high density optical storage channel, it is necessary to make an algorithm that the modulation code decoder must feed the LDPC decoder soft-valued information because LDPC decoder exploits soft values using the soft input. Therefore, we propose the soft-input soft-output run-length limited 17PP decoding algorithm and compare performance of LDPC codes. Consequently, we found that the proposed soft-inpt soft-output decoding algorithm using 17PP is 0.8㏈ better than the soft-inpt soft-output decoding algorithm using (1, 7) RLL.
