A merry-go-round decoding scheme for non-binary quasi-cyclic LDPC codes
Keke Liu, Juane Li, Shu Lin, Khaled Abdel-Ghaffar · 2014
This paper presents a reduced-complexity iterative scheme and an algorithm for decoding non-binary quasi-cyclic (QC) LDPC codes of a specific type. The proposed decoding scheme and the algorithm together significantly reduce the hardware implementation complexity of a decoder with no performance degradation. Also presented in the paper is a simple method for constructing a class of non-binary QC-LDPC codes.
