CORRECTION OF DEPENDENT ERRORS BY THE TURBOcodec based ON ATTACHED evenly convolutional codes

open access: yesDoklady Belorusskogo gosudarstvennogo universiteta informatiki i radioèlektroniki, 2019
The organization methods of dependent (packet) error correction by the turbocodecs based both on a sub systematic convolutional codes with uniform threshold decoding algorithm and recursive systematic convolutional codes are considered. The effectiveness

Minimal-memory realization of pearl-necklace encoders of general quantum convolutional codes

open access: yes, 2010
Quantum convolutional codes, like their classical counterparts, promise to offer higher error correction performance than block codes of equivalent encoding complexity, and are expected to find important applications in reliable quantum communication ...

The trellis complexity of convolutional codes [PDF]

open access: yes, 1995
Convolutional codes have a natural, regular, trellis structure that facilitates the implementation of Viterbi's algorithm. Linear block codes also have a natural, though not in general a regular, “minimal” trellis structure, which allows them to be ...

On codes induced from Hadamard matrices

open access: yesAIMS Mathematics
Unit derived schemes applied to Hadamard matrices are used to construct and analyse linear block and convolutional codes. Codes are constructed to prescribed types, lengths and rates and multiple series of self-dual, dual-containing, linear complementary

Woven Graph Codes: Asymptotic Performances and Examples

open access: yes, 2008
Constructions of woven graph codes based on constituent block and convolutional codes are studied. It is shown that within the random ensemble of such codes based on $s$-partite, $s$-uniform hypergraphs, where $s$ depends only on the code rate, there ...

Asymptotically good convolutional codes [PDF]

open access: yesLinear and Multilinear Algebra, 2018
In this paper, we construct new sequences of asymptotically good convolutional codes. These sequences are obtained from sequences of transitive, self-orthogonal and self-dual block codes that attain the Tsfasman-Vladut-Zink bound. Furthermore, by applying the techniques of expanding, extending, puncturing, direct sum, the |u|u+v| construction and the ...

Construction of a new class of (2k, k, 1) convolutional codes

open access: yesTongxin xuebao, 2014
A new class of (2k,k,1) convolutional codes are created by combining double cyclic codes and (2,1,1) convolu-tional codes, and also a new method for creation long codes with short ones was proposed.

There is no MacWilliams identity for convolutional codes [PDF]

open access: yes, 1977
An example is provided of two convolutional codes that have the same transmission gain but whose dual codes do not. This shows that no analog of the MacWilliams identity for block codes can exist relating the transmission gains of a convolutional code ...
