Some restrictions on the weight enumerators of near-extremal ternary self-dual codes and quaternary Hermitian self-dual codes
Makoto Araya, Masaaki Harada
We give restrictions on the weight enumerators of ternary near-extremal self-dual codes of length divisible by and quaternary near-extremal Hermitian self-dual codes of length…
Self-dual codes over and -extremal unimodular lattices
Masaaki Harada
New -extremal extremal unimodular lattices in dimensions , , and are constructed from self-dual codes over by Construction A. In the process of…
Construction of extremal Type II -codes
Masaaki Harada
We give methods for constructing many self-dual -codes and Type II -codes of length starting from a given self-dual -code and Type…
Construction of binary LCD codes, ternary LCD codes and quaternary Hermitian LCD codes
Masaaki Harada
We give two methods for constructing many linear complementary dual (LCD for short) codes from a given LCD code, by modifying some known methods for constructing self-dual codes. U…
On the classification of quaternary optimal Hermitian LCD codes
Makoto Araya, Masaaki Harada
We propose a method for a classification of quaternary Hermitian LCD codes having large minimum weights. As an example, we give a classification of quaternary optimal Hermitian LCD…
Remark on subcodes of linear complementary dual codes
Masaaki Harada, Ken Saito
We show that any ternary Euclidean (resp.\ quaternary Hermitian) linear complementary dual code contains a Euclidean (resp.\ Hermitian) linear complementary dual …
