초록

본 논문에서는, LDPC 부호를 위한 node-wise VCRBP의 개선된 기법인, 강제수렴 node-wise VCRBP와 부호기반 node-wise VCRBP를 제안한다. 두 가지 기법 모두 node-wise VCRBP에 비하여 매우 적은 오류 정정 성능 열화만으로 복호 복잡도와 대기시간을 현저하게 줄인다.

This paper proposes some new improved versions of node-wise VCRBP algorithm for low-density parity-check (LDPC) codes, called forced-convergence node-wise VCRBP algorithm and sign based node-wise VCRBP, both of which significantly reduce the decoding complexity and latency, with only negligible deterioration in error correcting performance.
