A serial concatenated scheme for LDPC code to achieve better error correction performance

2012 2nd International Conference on Consumer Electronics, Communications and Networks (CECNet), 2012
Low Density Parity Check(LDPC) Codes is a class of approaching limits error correction codes which has gained widely application in communications. The excellent performance, however, is the result of a large number of repeatedly conducting iterative decoding algorithm, and is apt to be seriously affected by small girth in the parity check matrix.

Comments on and Corrections to “On the Equivalence of Generalized Concatenated Codes and Generalized Error Location Codes” [Mar 00 642-649]

IEEE Transactions on Information Theory, 2017
In the works of Maucher et al. (200), Bossert et al. (1999) and GrieBer (2003), the authors presented the equivalence of generalized concatenated codes (GCC codes) and generalized error-location codes (GEL codes). However, they find that there exist several errors. In this work, the authors give several corrections to the work of Maucher et al.

Performance Analysis of Concatenated Error Correction Code in Secret Key Generation System

2019 IEEE 19th International Conference on Communication Technology (ICCT), 2019
Secret key generation from wireless channel is an emerging technique of physical layer security. At present, most of the secret key generation schemes use information reconciliation to obtain symmetric keys. This paper introduces a non-interactive information reconciliation scheme based on channel coding and stream encryption, and considering the error

Coded Modulation for Four-Dimensional Signal Constellations with Concatenated Non-Binary Forward Error Correction

2020 European Conference on Optical Communications (ECOC), 2020
A concatenated coded-modulation scheme for 4D constellations is proposed that consists of an inner complexity-optimized non-binary LDPC code and an outer zipper code. The related packing, shaping, and coding gains reduce the required SNR by 1 dB over conventional BICM with DP-16QAM.

FPGA Investigation on Error-Floor Performance of a Concatenated Staircase and Hamming Code for 400G-ZR Forward Error Correction

Optical Fiber Communication Conference Postdeadline Papers, 2018
With a record 200Gbps 50-piece-FPGA implementation, we investigate performance of a concatenated-staircase-Hamming code proposed for OIF-400GZR. FPGA emulations reveal an error flare at 10−10 BER lowering the predicted BER threshold from 1.25e-2 to 1.21e-2.

Concatenated error-correcting entropy codes and channel codes

IEEE International Conference on Communications, 2003. ICC '03., 2004
We propose a general class of concatenated error-correcting entropy codes and channel codes. In this way we extend and generalize the existing body of work on iterative decoding of entropy and channel codes. Using the structure and properties of serial concatenated codes, we employ error-correcting entropy codes as the outer code, and a convolutional ...

Concatenation of error-correcting codes and multiple transmit antennas

2000 IEEE International Symposium on Information Theory (Cat. No.00CH37060), 2002
Many wireless systems today employ error correcting coding. Adding transmit diversity may further improve the performance. We study the options to achieve the goal without significant change to the existing systems.

Degenerate asymmetric quantum concatenated codes for correcting biased quantum errors*

Chinese Physics B, 2021
In most practical quantum mechanical systems, quantum noise due to decoherence is highly biased towards dephasing. The quantum state suffers from phase flip noise much more seriously than from the bit flip noise. In this work, we construct new families of asymmetric quantum concatenated codes (AQCCs) to deal with such biased quantum noise.

Concatenated Synchronization Error Correcting Code with Designed Markers

2019 IEEE 5th International Conference on Computer and Communications (ICCC), 2019
A concatenated code with designed markers is proposed to detect and correct both synchronization and substitution errors. The inner decoder is effective in maintaining synchronization at codeword boundaries with the help of designed markers. The outer conventional error correcting code is used to provide adequate error correcting capability.

Error-Correcting WOM Codes: Concatenation and Joint Design

IEEE Transactions on Information Theory, 2019
We construct error-correcting write-once memory (WOM) codes that guarantee correction of any specified number of errors in $q$ -level memories. The constructions use suitably designed short $q$ -ary WOM codes and concatenate them with outer error-correcting codes over different alphabets using suitably designed mappings.
