Low latency LDPC hard‐decision algorithm for 5G NR

Abstract

In this study, the authors demonstrate the potential of hard-decision algorithm in industrial 5G NR channel coding. This study aims to show different forward error correction algorithms that can be expected in the context of cloud radio access network. Based on low density parity check (LDPC) min-sum (MS) algorithm, an improved hard-decision algorithm is proposed. The decoding process and performances are shown and compared with MS algorithm. To identify the advantage of this proposal, a test bench is launched in Cisco server using X86 chipset. Its results show a good trade-off between latency and performance.
