A Partial Parallel Architecture Encoder for QC-LDPC Coding

To meet the demand for quasi-cyclic low-density parity-check (QC-LDPC) codes, this paper proposes an encoder architecture specifically designed for QC-LDPC coding, compatible with the majority of QC-LDPC codes. The encoder is designed based on a forward substitution(FS) efficient coding algorithm, implemented in a partially parallel structure for efficient encoding,with the optimized encoder significantly improving hardware usage efficiency (HUE).
