研究了一种同时采用两种分集技术的通信方式。在给定的工作环境中,分析了双重分集系统的工作原理,以及信号的传输与接收的过程。并把本文研究的双重分集技术与单纯的空间分集、单纯的协作分集两种技术作了比较。最后通过理论分析与数值计算的结果表明,与单纯的协作分集和单纯的空间分集相比,本文研究的双重分集系统性能更为优越。
A communication method that uses both diversity techniques is studied. In a given working environment, the working principle of dual diversity system and the process of signal transmission and reception are analyzed. The comparison between the two techniques of this paper and those of simple space diversity and simple cooperation diversity is made. Finally, the theoretical analysis and numerical results show that the dual-diversity system proposed in this paper has better performance than simple cooperative diversity and pure spatial diversity.
