An [n,k,d]q code is a linear code of length n, dimension k and minimum weight d over the field of q elements. An [n,k,d]q code C is called extendable if C can be extended to an [n+1,k,d+1]q code. We give a new extension theorem for ternary linear codes. As an application, we prove the non-existence of [512,6,340]3 code, which is a new result.

三元线性码的一个新的扩展定理及其应用

一个 [ñķd]qcode是长度为n,尺寸为k且在q个元素的整个字段上的最小权重d的线性代码。一个[ñķd]qC称为可扩展,如果C 可以扩展到 [ñ+1个ķd+1个]q码。我们为三元线性码给出了一个新的扩展定理。作为一个应用程序,我们证明不存在[5126340]3 代码,这是一个新结果。
