Performance of ternary double circulant, double twistulant, and self-dual codes
T. Aaron Gulliver, Masaaki Harada
We study the performance of ternary isodual codes which are not self-dual and ternary self-dual codes, as measured by the decoding error probability in bounded distance decoding. W…
Self-dual codes and the non-existence of a quasi-symmetric 2-(37,9,8) design with intersection numbers 1 and 3
Masaaki Harada, Akihiro Munemasa, Vladimir D. Tonchev
We prove that a certain binary linear code associated with the incidence matrix of a quasi-symmetric 2-(37,9,8) design with intersection numbers 1 and 3 must be contained in an ext…
On the performance of optimal double circulant even codes
T. Aaron Gulliver, Masaaki Harada
In this note, we investigate the performance of optimal double circulant even codes which are not self-dual, as measured by the decoding error probability in bounded distance decod…
Supplementary difference sets related to a certain class of complex spherical 2-codes
Makoto Araya, Masaaki Harada, Sho Suda
In this paper, we study skew-symmetric - supplementary difference sets related to a certain class of complex spherical 2-codes. A classification of such supplementa…
The weight distribution of the self-dual polarity design code
Masaaki Harada, Ethan Novak, Vladimir D. Tonchev
The weight distribution of the binary self-dual code being the extended code of the code spanned by the incidence vectors of the blocks of the polarity desig…
On extremal double circulant self-dual codes of lengths -
T. Aaron Gulliver, Masaaki Harada
A classification of extremal double circulant self-dual codes of lengths up to is known. We give a classification of extremal double circulant self-dual codes of lengths $90,9…
