WIDESTARII卫星移动通信方案研究

Research on WIDESTAR II mobile communication scheme

WIDESTAR II系统为了更好的满足用户需求,在WIDESTAR系统的基础之上对移动终端、基站设备以及核心网节点进行了再次开发,从而实现了更高的传输速率以及与IMS或其他通用IP技术的灵活兼容。本文中,将首先对WIDESTAR II系统进行简要的介绍与分析,然后,对此系统所采用频谱效率提高方法、IP兼容技术以及时延降低策略等卫星移动通信机制进行研究与验证。

In order to better meet customer needs, WIDESTAR Ⅱ system based on the WIDESTAR system for mobile terminals, base station equipment and the development of core network nodes again, thus achieving higher transmission rates as well as other general IMS or IP flexible and compatible technology. In this paper,Will be the first to WIDESTAR Ⅱ system for brief introduction and analysis, then, To study and validate the system spectrum efficiency method, used by IP compatible technology as well as lower delay strategy such as satellite mobile communication system.
