MDS加性码的MacWilliams扩张定理

MacWilliams Extension Theorem for MDS additive codes

Serhii Dyshko

摘要:

MacWilliams扩张定理指出,线性码的每个线性等距都可以扩张到单项式映射。与线性码不同,加法码一般不具有扩张性质。本文在可加MDS码的情形下证明了可加码扩张定理的一个类似定理。更准确地说,它表明,几乎所有的添加剂MDS码的添加剂等距扩展到周围空间的等距。

英文摘要:

The MacWilliams Extension Theorem states that each linear isometry of a linear code extends to a monomial map. Unlike the linear codes, in general, additive codes do not have the extension property. In this paper, an analogue of the extension theorem for additive codes in the case of additive MDS codes is proved. More precisely, it is shown that for almost all additive MDS codes their additive isometries extend to isometries of the ambient space.
