Cross-Error Correcting Integer Codes over $\mathbb{Z}_{2^m}$

Abstract

In this work we investigate codes in $\mathbb{Z}_{2^m}^n$ that can correct errors that occur in just one coordinate of the codeword, with a magnitude of up to a given parameter $t$. We will show upper bounds on these cross codes, derive constructions for linear codes and respective decoding algorithm. The constructions (and decoding algorithms) are given for length $n = 2$ and $n = 3$, but for general $m$ and $t$.
