Construction of codes over a commutative non-unital ring from simplicial complexes and their applications

Vidya Sagar, Shikha Patel, Sanjay Kumar Singh

In this article, we investigate the construction of linear codes over a finite ring $S$ , where $S$ is taken to be an extension of a commutative non-unital ring…

On the Structure of Two-Dimensional Constacyclic Codes using Common Zero Sets

Vidya Sagar, Shikha Patel, Ashutosh Singh +1

We consider two-dimensional $(I^»_{1}, I^»_{2})$ -constacyclic codes over $F_{q}$ of area $M N$ , where $q$ is some power of prime $p$ with $g cd (M, p) = 1$ and $g cd (N, p) = 1$ . With t…

Decoding Algorithms for Two-dimensional Constacyclic Codes over $F_{q}$

Vidya Sagar, Shikha Patel, Shayan Srinivasa Garani

We derive the spectral domain properties of two-dimensional (2-D) $(I^»_{1}, I^»_{2})$ -constacyclic codes over $F_{q}$ using the 2-D finite field Fourier transform (FFFT). Based o…
