Concatenated Spatially Coupled LDPC Codes With Sliding Window Decoding for Joint Source-Channel Coding

open access: yesIEEE Transactions on Communications, 2022
In this paper, a method for joint source-channel coding (JSCC) based on concatenated spatially coupled low-density parity-check (SC-LDPC) codes is investigated.

Decodable quantum LDPC codes beyond the √n distance barrier using high dimensional expanders [PDF]

open access: yesSIAM journal on computing (Print), 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 ...

Evaluation of Low Density Parity Check Codes Over Various Channel Types [PDF]

open access: yesEngineering and Technology Journal, 2011
Low density parity check (LDPC) codes are one of the best error correcting codes in today’s coding world and are known to approach the Shannon limit. As with all other channel coding schemes, LDPC codes add redundancy to the uncoded input data to make it

Block Markov superposition transmission of LDPC codes

open access: yesJournal of Information and Intelligence, 2023
In this paper, based on the block Markov superposition transmission (BMST) technique, we present a new class of coupled low-density parity-check (LDPC) codes for the transport block (TB)-based transmission to improve the error-correcting performance. For

Efficient Design of Read Voltages and LDPC Codes in NAND Flash Memory Using Density Evolution

open access: yesIEEE Access, 2023
Low-density parity-check (LDPC) codes play an important role in the reliability enhancement of commercial NAND flash memory. Unfortunately, due to the requirement of the reading speed of NAND flash memory, the LDPC decoder will not obtain precise soft ...

GPU-Based, LDPC Decoding for 5G and Beyond

open access: yesIEEE Open Journal of Circuits and Systems, 2021
In 5G New Radio (NR), low-density parity-check (LDPC) codes are included as the error correction codes (ECC) for the data channel. While LDPC codes enable a low, near Shannon capacity, bit error rate (BER), they also become a computational bottleneck in ...
