中文摘要：

讨论了LA码的3个参数之间的关系,分析了LA码自相关函数与其自身参数K0之间的密切关系,推导并证明了LAS2000＋系统中LA码自相关函数比较理想时K0〉98是必须满足的1个充分条件. 这个充分条件对LA码的序列设计和采用LA码的系统帧结构的设计都有着重要的意义.

英文摘要：

The relations among three parameters of LA code and the relations between the auto-correlation function and the parameter K0 of the LA code are investigated. It is proven that K0 〉98 is a sufficiency condition when the autocorrelation function of the LA code in LAS2000 ＋ system is on ideal state. This sufficiency condition is important for the design of LA code and the frame structure of the system in which LA code is used.
