7.7Gbps encoder design for IEEE 802.11n/ac QC-LDPC codes [PDF]
2012 International SoC Design Conference (ISOCC), 2012 This paper proposes a high throughput encoding process and encoder architecture for quasi-cyclic low-density parity-check (QC-LDPC) codes in IEEE 802.11n/ac standards. In order to achieve the high throughput with low complexity, a partially parallel processing based encoding process and encoder architecture are proposed.

Rate‐compatible QC‐LDPC codes based on PEXIT [PDF]
Electronics Letters, 2018 An improved extension method based on protograph extrinsic information transfer (PEXIT) charts is proposed to design rate‐compatible quasi‐cyclic low‐density parity‐check (QC‐LDPC) codes with more flexible rates and better performance. The masking matrix of the highest‐rate code can first be constructed column by column to own the lowest decoding ...

A High Throughput Implementation of QC-LDPC Codes for 5G NR
IEEE Access, 2019 Quasi-cyclic low-density parity-check (QC-LDPC) codes are the choice for data channels in the fifth generation (5G) new radio (NR). At the transmitter side, code bits from the QC-LDPC encoder are delivered to the rate matcher.

On a class of column‐weight 3 decomposable LDPC codes with the analysis of elementary trapping sets
IET CommunicationsA column‐weight k LDPC code with the parity‐check matrix H is called decomposable if there exists a permutation π on the rows of H, such that π(H) can be decomposed into k column‐weight one matrix.

Parity-Check Matrix Partitioning for Efficient Layered Decoding of QC-LDPC Codes [PDF]
IEEE Transactions on Communications, 2022 In this paper, we consider how to partition the parity-check matrices (PCMs) to reduce the hardware complexity and increase decoding throughput for the row layered decoding of quasi-cyclic low-density parity-check (QC-LDPC) codes. First, we formulate the
