协作通信技术在卫星移动通信中的应用

Application of cooperative communication technology in satellite mobile communication

卫星移动通信自逐渐发展以来,便因其覆盖范围广、地域限制弱、信号容量大等特点被广泛应用于通信网络当中,成为全球通信网络中不可或缺的有效信息传输手段之一,在军用领域和民用领域发挥着重要作用。但由于卫星移动通信的信道受多径效应、阴影效应以及多普勒效应的影响,严重的影响信号传输的有效性,因此必须采用相关的通信技术克服这一问题。协作通信技术作为提高通信质量的有效手段,因此研究其在卫星移动通信中的应用逐渐成为热门话题。

Satellite mobile communication since gradually since the development,because of its cover a wide range,weak geographical restrictions,signal capacity and is widely used in communication network,has become one of the global communications network is an effective means of information transmission,in the military field and civilian field plays an important role. But because of the influence of satellite mobile communication channels affected by multi-path effect and shadow effect and Doppler effect,the effectiveness of the serious influence on the transmission of the signal.Therefore,it is necessary to use related communications technologies to overcome this problem. Cooperative communication technology,as an effective way to improve the quality of communication.Therefore, the study of its application in satellite mobile communication has gradually become the hot topic.
