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…
Cross-Attention Message-Passing Transformers for Code-Agnostic Decoding in 6G Networks
Seong-Joon Park, Hee-Youl Kwak, Sang-Hyo Kim +2
Channel coding for 6G networks is expected to support a wide range of requirements arising from heterogeneous communication scenarios. These demands challenge traditional code-spec…
Lowering the Error Floor of Error Correction Code Transformer
Taewoo Park, Seong-Joon Park, Hee-Youl Kwak +2
With the success of transformer architectures across diverse applications, the error correction code transformer (ECCT) has gained significant attention for its superior decoding p…
Neural Window Decoder for SC-LDPC Codes
Dae-Young Yun, Hee-Youl Kwak, Yongjune Kim +2
In this paper, we propose a neural window decoder (NWD) for spatially coupled low-density parity-check (SC-LDPC) codes. The proposed NWD retains the conventional window decoder (WD…
