为提高多中继协作通信系统可靠性,将定向天线和多中继协作通信系统相结合,提出基于定向天线的解码转发最佳中继选择协作策略。首先理论推导出定向发送—定向接收模式下通信系统中断概率闭合表达式,并推导出定向发送—全向接收、全向发送—全向接收模式下的系统中断概率计算式。然后对3种模式下,协作通信系统中断概率和信噪比、中继节点数、天线增益、信道衰落系数以及信道容量之间的关系进行了数值仿真分析。理论分析和仿真结果表明,采用定向天线的协作通信系统可以有效降低协作通信系统中断概率,提高频谱利用率,并且存在最佳中继节点和最优功率分配系数使得中断概率进一步下降。
In order to achieve reliable communication in multi-relay cooperative communication,the directional antenna combining multi-relay cooperative communication system and optimal relay selection decode-and-forward cooperative strategy was presented.Firstly,the theoretical closed form of outage probability of the communication system using directional antenna operating in the three modes of DT-DR,DT-OR and OT-OR were presented.Then for three kinds mode,the collaboration communication system interrupt probability and signal-to-noise ratio,the number of relay nodes,the antenna gain channel fading efficiency and relationship between the channel capacity were analyzed in numerical simulation.These findings reveal that excellent performance of cooperative communication system with directional antennas could be achieved such as smaller outage probability and improved by best relay nodes and optimal power allocation coefficient.
