A revolving iterative algorithm for decoding algebraic quasi-cyclic LDPC codes
Keke Liu, Shu Lin, Khaled Abdel-Ghaffar · 2013
An effective reduced-complexity min-sum algorithm for decoding algebraic quasi-cyclic LDPC codes is presented. The proposed decoding algorithm significantly reduces the hardware implementation complexity, the size of memory required to store information, and the computational complexity of a decoder with no or a small loss in performance compared to the scaled min-sum algorithm.
