它确实是所有线性码的基本构造

It is indeed a fundamental construction of all linear codes

Can Xiang

摘要:

线性码广泛用于通信系统、消费电子产品和存储设备中。有限域上的所有线性码都可以由生成矩阵生成。因此,生成矩阵方法被称为线性码的基本构造。这是唯一已知的可以在有限域上产生所有线性码的构造方法。近年来,有限域上线性码的定义集构造引起了人们的广泛关注,并被用来构造大量的有限域上线性码。有人声称,这种方法也可以生成有限域上的所有线性码。但到目前为止,在文献中还没有证据证明这一说法。本文的目的是证明这一说法,并确认定义集的方法确实是一个基本的方法来构造所有的线性码在有限域上。作为副产品,有限域上的所有线性码的迹表示。

英文摘要:

Linear codes are widely employed in communication systems, consumer electronics, and storage devices. All linear codes over finite fields can be generated by a generator matrix. Due to this, the generator matrix approach is called a fundamental construction of linear codes. This is the only known construction method that can produce all linear codes over finite fields. Recently, a defining-set construction of linear codes over finite fields has attracted a lot of attention, and have been employed to produce a huge number of classes of linear codes over finite fields. It was claimed that this approach can also generate all linear codes over finite fields. But so far, no proof of this claim is given in the literature. The objective of this paper is to prove this claim, and confirm that the defining-set approach is indeed a fundamental approach to constructing all linear codes over finite fields. As a byproduct, a trace representation of all linear codes over finite fields is presented.
