摘　　要：针对单播和广播同时存在的网络,设计开发一种单广播干扰信道(IC)并存的网络系统,研究干扰消息对系统空间复用增益的影响和系统的天线效率问题。为实现接收机能够同时迫零多个干扰消息,在接收机运用零空间的交和迫零干扰消息的新方法来进行处理。对此网络模型进行分析,得到系统的空间复用增益和天线效率的一般化结果,以及最优天线配置方案。最后使用MATLAB对系统进行仿真实验,得到系统的和速率及天线效率的仿真结果,实验验证仿真实验的结果和对系统进行理论分析所得结果保持一致。Aiming at the network with unicast and broadcast,designs and develops an interference channel coexisting network,studies the influence of interference message on spatial multiplexing gain and the antenna efficiency.In order to realize that the receiving end can force more than one interference message at the same time,the new method of nullspace intersection and zero-forcing is used.The optimal antenna configuration scheme,the generalization results of the spatial multiplexing gain and antenna efficiency are obtained.Finally,the simulation results of the sum rate and the antenna efficiency are obtained by the experiment in MATLAB which shows that the simulation results are consistent with the theoretical analysis of the system.
