摘　　要：在分析MF-TDMA体制特点基础上,结合新的数字化实现水平和滤波多音调制技术,提出了一种优化的多频时分多址卫星通信体制FMT-TDMA。对滤波多音调制技术进行了简要介绍,并与正交频分复用技术进行了比较,给出了各自的优缺点,分析了FMT-TDMA体制下的多点对多点网状组网和广播通信机理,设计了帧结构,最后结合示例给出了多类站型混合组网应用和信道资源管理方法。Based on analysis of MF-TDMA characteristics,filtered muhitone（FMT） modulation and new implement technology de- velopment,an optimized MF-TDMA satellite communication network is proposed. Firstly,the FMT modulation technology is introduced and compared with OFDM,and its advantages and disadvantages are given. Then mesh topology and broadcast communication principles of FMT-TDMA communication system are analyzed. The hybrid topology network specialty and application scenario are analyzed. At last, the multi-carrier frame structure, multi-type stations application scenario and the method of slot channel resource management are presented.
