Design of Outage-Limit-Approaching Protograph LDPC Codes via Generalized Rootchecks
Inki Kim, Hyuntae Ahn, Yongjune Kim +3
This paper presents a new protograph-based LDPC code design framework that simultaneously achieves full diversity over block-fading channels (BFCs) and near-capacity performance ov…

5G LDPC Codes as Root LDPC Codes via Diversity Alignment
Hyuntae Ahn, Inki Kim, Hee-Youl Kwak +3
This paper studies the diversity of protographbased quasi-cyclic low-density parity-check (QC-LDPC) codes over nonergodic block-fading channels under iterative beliefpropagation de…
