Algorithms of self-synchronizing single-deletion-correcting codes
Whan-Hyuk Choi
This study explores the self-synchronization problem in DNA coding, specifically addressing single-deletion errors without using delimiters between codewords. We aim to identify th…
Extending binary linear codes to self-orthogonal codes
Jon-Lark Kim, Whan-Hyuk Choi
Kim et al. (2021) gave a method to embed a given binary code into a self-orthogonal code of the shortest length which has the same dimension …
An improved upper bound on self-dual codes over finite fields , and
Whan-Hyuk Choi, Jon-Lark Kim
This paper gives new methods of constructing {\it symmetric self-dual codes} over a finite field where is a power of an odd prime. These methods are motivated by the we…
Self-dual codes over with symmetric generator matrices
Whan-Hyuk Choi, Jon-Lark Kim
We introduce a consistent and efficient method to construct self-dual codes over with symmetric generator matrices from a self-dual code over of smaller length wher…
