Low-Latency High-Throughput Decoder of QC-LDPC Codes by Matrix Splitting
International Conference on Wireless Communications and Signal ProcessingAs the continuously increasing demand of high data rate and lower transmission, many modern communication systems employ the LDPC coding scheme with ultra-high throughput decoder to achieve these challenging requirements.

Performance Analysis of Practical QC-LDPC Codes: From DVB-S2 to ATSC 3.0
IEEE transactions on broadcasting, 2019In this paper, a new analysis method is introduced to predict the gap between Shannon limit and successful decoding signal-to-noise ratio threshold (SNR loss) of practical quasi-cyclic low-density parity check (QC-LDPC) codes.

Construction of Girth-8 QC-LDPC Codes Free of Small Trapping Sets
IEEE Communications Letters, 2019In this letter, we propose a new technique to design quasi-cyclic low-density parity-check (QC-LDPC) codes with girth 8 and variable node degrees 3 and 4.

Improved PEG construction of large girth QC-LDPC codes
2016 9th International Symposium on Turbo Codes and Iterative Information Processing (ISTC), 2016In this paper, we present an improvement of the PEG algorithm for constructing quasi-cyclic low-density parity-check (QC-LDPC) codes with large girth. We introduce the concept of PEG-undetectable cycles on the computation tree in the PEG algorithm for QC-LDPC codes and give a predictive method to avoid these undetected cycles. The aim is to select only

Nonbinary Quasi-Regular QC-LDPC Codes Derived From Cycle Codes
IEEE Communications Letters, 2016Nonbinary ultra sparse codes, particularly regular cycle codes, are known to approach Shannon-limit performance as the Galois field $ \mathrm {GF}(q)$ order is sufficiently large. Good cycle codes can result from a class of algebraically defined graphs called cages.
