摘要
阐述了对流层散射信道恶劣的传输环境以及其多径衰落特性。介绍了MIMO技术的基本原理,分析了MIMO系统的模型以及信道容量。运用Matlab/Simulink对MIMO技术在散射通信中的性能进行了仿真。仿真结果表明,应用MIMO技术能够有效地提高对流层散射通信系统的容量和性能,降低误码率,提高通信的可靠度。
This paper indicates the bad transmission environment and multipath fading characteristic of troposcatter communication.The basic theory of MIMO is introduced,and its model and channel capacity analyzed.The performance simulation of MIMO in troposcatter communication based on MATLAB/Simulink shows that MIMO could increase the capacity and performance of the troposcatter communication and enhance the reliability of the communication by reducing BER effectively.
