Iterative LDPC-LDPC product code for bit patterned media
2016 Asia-Pacific Magnetic Recording Conference Digest (APMRC), 2016Bit patterned media implements high density recording of more than 10 Tera-bits per square inch, but burst error can be a serious problem. Burst errors are occurred by media defect and data write failure. However, if burst errors are erasure compensated,

Protograph LDPC-Coded BICM-ID With Irregular CSK Mapping in Visible Light Communication Systems
IEEE Transactions on Vehicular Technology, 2021This paper designs and analyzes the bit-interleaved coded modulation with iterative demapping and decoding (BICM-ID) framework under color-shift-keying (CSK) modulation to achieve spectrally efficient transmissions in visible light communication (VLC ...

Design of High-Performance and Area-Efficient Decoder for 5G LDPC Codes
IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2021Low-density parity-check (LDPC) code as a very promising error-correction code has been adopted as the channel coding scheme in the fifth-generation (5G) new radio.

Fiber bundle codes: breaking the n1/2 polylog(n) barrier for Quantum LDPC codes
Symposium on the Theory of Computing, 2020We present a quantum LDPC code family that has distance Ω(N3/5/polylog(N)) and Θ(N3/5) logical qubits, where N is the code length. This is the first quantum LDPC code construction that achieves distance greater than N1/2 polylog(N).

Spatially Coupled LDPC Codes via Partial Superposition and Their Application to HARQ
IEEE Transactions on Vehicular Technology, 2021This paper proposes a new class of spatially coupled codes, which are constructed by sending codewords of a low-density parity-check block code (LDPC-BC) in a block Markov superposition transmission (BMST) manner, resulting in the BMST-LDPC codes ...

Irregular LDPC codes as concatenation of regular LDPC codes
IEEE Communications Letters, 2005In 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 ...

Exploiting Asymmetric Errors for LDPC Decoding Optimization on 3D NAND Flash Memory
IEEE transactions on computers, 2020By 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.

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 ...
