摘要
针对对流层散射通信系统存在信道传播损耗大和具有快慢衰落特性等问题,首先提出了利用分集接收技术来克服这些衰落特性,然后对分集技术中的三种主要分集技术进行了比较,通过比较得到空间分集是最适合的一种技术。基于此,研究了空间分集在多天线系统中的应用,最后给出了散射通信的发展前景。
In view of the problems of large channel propagation loss and fast and slow fading characteristics in the tropospheric scattering communication system.Firstly,the diversity receiving technology is used to overcome these fading characteristics,and then the three main diversity technologies in the diversity technology are compared,and the spatial diversity which is obtained by comparison is the most suitable technology.Based on this,the application of space diversity in a multi-antenna system is studied,and the development prospect of scattering communication is proposed.
