A novel method for encoding and decoding based on enhanced parity-check-concatenated polar codes
Dianxin kexue, 2021 Polar codes have perfect coding and decoding performance as a kind of error correction code, which have become a standard coding scheme for 5G short code control channel. While the length of polar codes is short, its performance is not good enough.

Parallel Concatenated Block Codes Constructed by Convolutional Interleavers
IEEE Access, 2021 This paper presents the application of convolutional interleavers for constructing high performance parallel concatenated block (PCB) codes. The utilized interleaver is operated as a block interleaver, when the number of stuff bits is applied at the ...

From concatenated codes to graph codes [PDF]
Manufacturing Engineer, 2005 We consider codes based on simple bipartite expander graphs. These codes may be seen as the first step leading from product type concatenated codes to more complex graph codes. We emphasize constructions of specific codes of realistic lengths, and study the details of decoding by message passing in trees.

Combined Serially Concatenated Codes and MMSE Equalization: an EXIT Chart Aided Perspective
, 2006 Iterative Minimum Mean Square Error (MMSE) equalization and channel decoding is appealing, since it exhibits a lower complexity than maximum a posteriori (MAP) turbo equalization.

Code-Based Cryptography With Generalized Concatenated Codes for Restricted Error Values
IEEE Open Journal of the Communications Society, 2022 Code-based cryptosystems are promising candidates for post-quantum cryptography. Recently, generalized concatenated codes over Gaussian and Eisenstein integers were proposed for those systems. For a channel model with errors of restricted weight, those q-

Throughput enhancing concatenated codes [PDF]
IET Communications, 2019 Traditionally, concatenation of codes is used to increase the coding gain at the expense of the code rate and the throughput. In contrast, throughput enhancing concatenated codes (TECCs) are constructed here aiming to increase the throughput.

High performance short-block binary regular LDPC codes
Alexandria 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 ...

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

Coding in the existential theory of concatenation
Archiv für Mathematische Logik und Grundlagenforschung, 1987 The authors show that every existentially definable relation over concatenation is diophantine. They define a 647 (1987; Zbl 0639.03057).

H.264 wireless video telephony using iteratively-detected binary self-concatenated coding [PDF]
, 2010 In this contribution we propose a robust H.264 coded wireless video transmission scheme using iteratively decoded self-concatenated convolutional coding (SECCC). The proposed SECCC scheme is composed of constituent recursive systematic convolutional (RSC)
