High performance short-block binary regular LDPC codes

open access: yesAlexandria Engineering Journal, 2018
LDPC code shows a good performance with long-block codes. However, certain channels are constrained to use short-block codes due to latency. Therefore, concatenated LDPC codes with iterative decoding is a good choice to get a good performance ...

Binary Multilevel Convolutional Codes with Unequal Error Protection Capabilities [PDF]

open access: yes, 1998
Binary multilevel convolutional codes (CCs) with unequal error protection (UEP) capabilities are studied. These codes belong to the class of generalized concatenated (GC) codes. Binary CCs are used as outer codes.

Construction of asymptotically good low-rate error-correcting codes through pseudo-random graphs [PDF]

open access: yes, 1991
A novel technique, based on the pseudo-random properties of certain graphs known as expanders, is used to obtain novel simple explicit constructions of asymptotically good codes.

Some Results on Images of a Class of λ-Constacyclic Codes Over Finite Fields

open access: yesIEEE Access, 2020
In this paper, we show that any λ-constacyclic code over Fqm is a λ-constacyclic code over Fq under some special maps. Moreover, we show that the images of these λ_constacyclic codes can be put into the concatenated form.

Analysis of Near-Capacity Iterative Decoding Schemes for Wireless Communication Using EXIT Charts

open access: yesIEEE Access, 2020
This article proposes and compares the performance of three flexible and bandwidth efficient transceivers. The terminology of Over-Complete Mapping (OCM) is introduced in the first two schemes.

Reduced complexity hard‐ and soft‐input BCH decoding with applications in concatenated codes

open access: yesIET Circuits, Devices and Systems, 2021
Error correction coding for optical communication and storage requires high rate codes that enable high data throughput and low residual errors. Recently, different concatenated coding schemes were proposed that are based on binary BCH codes with low ...

Improved DC-Free Run-Length Limited 4B6B Codes for Concatenated Schemes

open access: yesIEEE Access, 2022
In this letter, we introduce a class of improved DC-free 4B6B codes in terms of error correction capabilities for a serially concatenated architecture. There are billions of different codebooks that can be derived from the 16 codewords contained in the ...

Low-Complexity Concatenated LDPC-Staircase Codes [PDF]

open access: yesJournal of Lightwave Technology, 2018
A low-complexity soft-decision concatenated FEC scheme, consisting of an inner LDPC code and an outer staircase code, is proposed. The inner code is tasked with reducing the bit error probability below the outer-code threshold.

Qubit-Oscillator Concatenated Codes: Decoding Formalism and Code Comparison

open access: yesPRX Quantum, 2023
Concatenating bosonic error-correcting codes with qubit codes can substantially boost the error-correcting power of the original qubit codes. It is not clear how to concatenate optimally, given that there are several bosonic codes and concatenation ...

Concatenating Binomial Codes with the Planar Code

open access: yes, 2023
Rotation symmetric bosonic codes are an attractive encoding for qubits into oscillator degrees of freedom, particularly in superconducting qubit experiments. While these codes can tolerate considerable loss and dephasing, they will need to be combined with higher level codes to achieve large-scale devices.
