| 摘 要： | 卫星移动通信作为地面移动通信的补充，是实现全球个人通信的必不可少的手段之一，同时也是目前发展最迅速的通信技术之一．卫星移动通信具有卫星固定业务和移动通信双重特点，其电波传输距离远，经历的环境特殊，导致其信道特性远比地面系统复杂．因此，研究其信道特性是设计出高效实用的通信系统的关键环节．本对其信道特性进行了具体深入的分析，并对某些衰减因素的解决措施作了简要探讨．

| Abstract: | As a complement of land-mobile communication,mobile satellite communication is an essential method to achieve global personal communication. Meanwhile,it is also one of the communication technologies that develop fastest now.Mobile satellite communication has double trait of both fixed satellite service and mobile communication.The transmission of its electric wave has the trait of long distance and special environment.This lead to that its channel property is more complex than land-mobile system.Thus,it is a key part to study its channel property for designing an efficient?practical communication system.This paper has done a special?deep analysis of its channel property and has discussed some settlements on certain loss factors. |

| Keywords: | mobile satellite communication channel property transmission loss Doppler frequency shift |
