PERSYMMETRIC MATRIX AND ITS APPLICATION IN CODING THEORY

Barekeng
A persymmetric matrix is a square matrix that is symmetric concerning its antidiagonal. This article discusses some characteristics of a persymmetric matrix and its application in coding theory. A persymmetric matrix is used to form a generator matrix of

Reversible Self-Dual Codes over Finite Field

Cauchy: Jurnal Matematika Murni dan Aplikasi
Reversible self-dual code is a linear code which combine the properties from self-dual code and reversible code. Previous research shows that reversible self-dual codes have only been developed over field of order 2 and order 4.

Some results on free Euclidean self-dual codes over F2+vF2

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2019
In thispaper, free Euclidean self-dual codes over the ring F2+ v F2 with v2=vof order 4 are considered. A necessary andsufficient condition for the form of the generator matrix of a free Euclideanself-dual code is given.

Luby Transform Coding Aided Bit-Interleaved Coded Modulation for the Wireless Internet [PDF]

, 2007
Bit-Interleaved Coded Modulation using Iterative Decoding (BICM-ID) is amalgamated with Luby Transform (LT) coding. The resultant joint design of the physical and data link layer substantially improves the attainable Bit Error Rate (BER) performance.

Perturbation analysis of Markov modulated fluid models

, 2016
We consider perturbations of positive recurrent Markov modulated fluid models. In addition to the infinitesimal generator of the phases, we also perturb the rate matrix, and analyze the effect of those perturbations on the matrix of first return ...
