PAS系统关键技术及终端写码方式

Some key technologys of the PAS system and some ways of the terminal writing codes

介绍了PAS的系统关键技术:频率使用与多址、微蜂窝与信道动态分配、V5接口、越区切换与漫游、鉴权与调制方式等技术。阐述了PAS终端不同于GSM和CDMA终端的特性及PAS终端的独特写码方式。

Some key technologys of the PAS system are introduced in detail in this paper: such as the use of frequency and multi-access, micro cells and active distribution of the channels, V5 interface, data exchange across cells and ATC, authentication and the ways of modulation and so on. The Characteristics in which terminal of PAS is different from the terminal of GSM and CDMA are elaborated, and the special ways of writing codes for the terminal of PAS are introduced.
