Comprehensive Study on CC-LDPC, BC-LDPC and Polar Code
2020 IEEE Wireless Communications and Networking Conference Workshops (WCNCW), 2020Channel coding scheme is very crucial for the next sixth generation (6G) mobile communication. In this paper, we investigate the encoding and decoding methods of the state-of-the-art channel codes, which include the convolutional code LDPC (CC-LDPC), block code LDPC (BC-LDPC) and polar code to access the benefits from CC-LDPC.

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 ...

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).

Iterative LDPC-LDPC product code for bit patterned media
2016 Asia-Pacific Magnetic Recording Conference Digest (APMRC), 2016Bit patterned media aims at high density recording of more than 10 Tb per square inch, but a burst error mostly occurred by media defects, and data write failure can be a serious problem. However, if the burst errors are compensated by erasure decoding, the performance of low-density parity check (LDPC) code, which is a strong candidate for the error ...

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 ...

The raw error rate of a Solid-State drive (SSD) increases gradually with the increase of Program/Erase (P/E) cycles, retention time, and read cycles. Traditional approaches often use Error Correction Code (ECC) to ensure the reliability of SSDs.
