Using Error Modes Aware LDPC to Improve Decoding Performance of 3-D TLC NAND Flash
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 20203-D triple-level cell (3-D TLC) NAND flash has high storage density and capacity, but degrading data reliability due to high raw bit error rates induced by a certain number of program/erase cycles. To guarantee data reliability, low-density parity-check (

Enumerators for Protograph-Based Ensembles of LDPC and Generalized LDPC Codes
IEEE Transactions on Information Theory, 2011Protograph-based LDPC and generalized LDPC (G-LDPC) codes have the advantages of a simple design procedure and highly structured encoders and decoders. The design of such “protograph-based codes” relies on what is effectively a computer-based search. As such, following Gallager, it is prudent to restrict the search to a “good ensemble,” for example, an

LDPC Decoding on the Intel SCC
2012 20th Euromicro International Conference on Parallel, Distributed and Network-based Processing, 2012Low-Density Parity-Check (LDPC) codes are powerful error correcting codes used today in communication standards such as DVB-S2 and WiMAX to transmit data inside noisy channels with high error probability. LDPC decoding is computationally demanding and requires irregular accesses to memory which makes it suitable for parallelization.

The rate of regular LDPC codes
IEEE International Symposium on Information Theory, 2003. Proceedings., 2003We find the rate of a typical code from the regular low-density parity-check (LDPC) ensemble. We then show that the rate of a code from the ensemble converges to the design rate in quadratic mean and almost surely.

Design of optimal LDPC code for the system of GMSK concatenated with LDPC codes
2011 2nd International Conference on Control, Instrumentation and Automation (ICCIA), 2011This paper mainly concerns on the continuous phase modulation system of GMSK concatenated with LDPC codes. Decomposing GMSK signal into differential coding and PAM modulating manner, we analyze the iterative demodulating and decoding principle and design optimal LDPC codes based on EXIT chart.

An LDPC decoder architecture for multi-rate QC-LDPC codes
2011 IEEE 54th International Midwest Symposium on Circuits and Systems (MWSCAS), 2011This paper presents a partially parallel LDPC decoder architecture for QC-LDPC codes. In particular, we introduce a check node processing element which is 3-parallel, adjustable to irregular inputs and easily expandable. Furthermore, our decoder is applicable to multi-rate system by simply writing additional data to internal RAM.

7th IEEE International Conference on Computer and Information Technology (CIT 2007), 2007
In light of the history of LDPC codes and relevant research advances in recent years, this paper probes into the encoding and decoding techniques related to this capacity-approaching error-correction technology. Besides the general expression as an equation, LDPC codes can also be examined with a Tanner graph.

Block-LDPC: a practical LDPC coding system design approach
IEEE Transactions on Circuits and Systems I: Regular Papers, 2005This paper presents a joint low-density parity-check (LDPC) code-encoder-decoder design approach, called Block-LDPC, for practical LDPC coding system implementations. The key idea is to construct LDPC codes subject to certain hardware-oriented constraints that ensure the effective encoder and decoder hardware implementations.

Efficient Quantum Stabilizer Codes: LDPC and LDPC-Convolutional Constructions
IEEE Transactions on Information Theory, 2010Existing quantum stabilizer codes constructed from the classic binary codes exclusively belong to the special subclass of Calderbank-Shor-Steane (CSS) codes. This paper fills in the gap by proposing five systematic constructions for non-CSS stabilizer codes, the first four of which are based on classic binary quasi-cyclic low-density parity-check (LDPC)
