基于定向天线的DF协同通信技术研究

内容简介：对基于定向天线的DF协同通信系统进行了研究。提出了几种不同DDF协同通信方式，通过对这些通信方式的分析，推导出了它们的中断概率表达式，并仿真对比了各种方式中断概率的异同。结果表明，反馈及选择DDF系统可以获得满分分级增益，在频谱效率不高的情况下反馈DDF系统能获得最优的中断性能。

Abstract：DF cooperative communication system based on directional antenna is studied. Several different directional DF cooperative communication methods are proposed. Through the analysis of these communication methods,the expressions of the outage probabilities are derived,and the difference of the outage probabilities are compared by simulation. The results show that directional DF system with feedback and selection can obtain full diversity gains. Directional DF system with feedback is of the optimal outage performance when spectral efficiency is not high enough.
