In addition, we proved that a maximal prefix code with finite length that contains the alphabet in X must be a maximal code. 同时,证明了满足含有X中字母且长度有限的极大前缀码必是极大码。
Several Spread Spectrum codes ( PN code) are introduced in this paper especially the Maximal Length code ( m code). 本文介绍了几种扩频编码(PN码),重点介绍了最大长度线性移存器序列码(m序列码)。
In this paper, we shall introduce the notion of fuzzy code, fuzzy prefix code, and maximal prefix code, and discuss their algebraic character and algebraic properties. 在自由么半群上引进了模糊码、模糊前缀码和模糊极大前缀码等概念,并且讨论了它们的某些代数特征和代数性质。
Let X~ be the free monoid over finite alphabet set X, let X~ as node set constitute a language diagram, then use it to investigate maximal prefix code, and obtain a tie of sufficiency and necessary conditions of discriminating maximal prefix code. 设X是有限字母集X上的自由幺半群,以X为顶点集构造一个语言图,用它来研究极大前缀码,并给出一系列判定极大前缀码的充要条件。
In this paper it is proved that an equidistant code over an arbitrary finite field is equivalent to the repeated code of a maximal projective code. The complete construction of equidistant linear code is given. 本文证明任意有限域上的一个线性等距码等价于一个极大投射码的重复码,从而给出了一般q元线性等距码的全部结构。
Some determinations and properties of the maximal prefix code 极大前缀码的若干判定与性质
In this paper we give the following results: ( 1) Every group is a syntactic monoid of language X with X being a maximal strong code; 研究强码,得到以下三个结果:(1)任意一个群都可以成为X~的句法么半群,其中X是某个极大强码;
The top displacement of tower on the hilltop is maximal. However, the offset of insulator which is suspended on the tower located on the hillside is maximal. The unbalanced tension to check the tower in mountainous areas in the code is relative small which is unsafe. 相同风速下,一般是位于山顶的铁塔塔顶位移最大,而位于山腰的绝缘串偏移最大,规范规定的验算山区输电塔不平衡张力的取值偏小。
