Exploiting Asymmetric Errors for LDPC Decoding Optimization on 3D NAND Flash Memory

IEEE transactions on computers, 2020
By stacking layers vertically, the adoption of 3D NAND has significantly increased the capacity for storage systems. The complex structure of 3D NAND introduces more errors than planer flash.

Flexible High Throughput QC-LDPC Decoder With Perfect Pipeline Conflicts Resolution and Efficient Hardware Utilization

IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2020
Modern communication standards, such as 5G new radio (5G NR), require a high speed decoder for highly irregular quasi-cyclic low density parity check (QC-LDPC) codes.

Decodable quantum LDPC codes beyond the square root distance barrier using high dimensional expanders

IEEE Annual Symposium on Foundations of Computer Science, 2020
Constructing quantum LDPC codes with a minimum distance that grows faster than a square root of the length has been a major challenge of the field. With this challenge in mind, we investigate constructions that come from high-dimensional expanders, in ...

Irregular LDPC codes as concatenation of regular LDPC codes

IEEE Communications Letters, 2005
In this letter, the construction of irregular LDPC codes obtained by concatenating regular ones is considered. These codes are analyzed for the binary symmetric channel (BSC). It is shown via proper distribution evolution that such concatenated codes have in general a threshold value weaker (but not necessarily much different) than their unconstrained ...

Block-LDPC: a practical LDPC coding system design approach

IEEE Transactions on Circuits and Systems I: Regular Papers, 2005
This 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.

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, 2020
3-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 (

Efficient Quantum Stabilizer Codes: LDPC and LDPC-Convolutional Constructions

IEEE Transactions on Information Theory, 2010
Existing 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)

Blind Identification of LDPC Code Based on Deep Learning

International Conferences on Dependable Systems and Their Applications, 2020
In cognitive radio or military communications systems, the receiver usually needs to blindly identify which LDPC code has been adopted by the transmitter. Existing methods for blind LDPC code identification suffer from high computational complexity. This
