中文摘要：
卫星宽带通信已成为目前研究的热点。现有的DVB-RCS卫星无线接入标准以物理层规范为主,尚未构成完整的卫星宽带无线接入体系。本文基于DVB-RCS技术,针对卫星宽带无线接入的需求和特点,结合地面WiMAX宽带无线接入技术,给出了卫星宽带无线接入体系的功能架构设计,并具体分析了各主要功能的设计与实现方法。
英文摘要：
Satellite broadband communications have become one of hot issues. The existing satellite wireless access standard DVB-RCS is concentrated on physical layer technique criterions, however, a systemic framework of satellite broadband access system has not been proposed. This paper analyzes requirements and characteristics of satellite broadband access system, and a functional framework of which is also proposed based on the DVB-RCS standard and WiMAX terrestrial broadband access technique. Furthermore, the designing and realization methods of main functions of this proposed framework are researched.
