摘要/Abstract

摘要： 提出一种多用户BC单播与BC多播并存的网络模型以及结合零空间交的迫零干扰消息的新方法,该模型的主网采用“循环模式” 为接收端分配期望消息,以构成多播网络;次网采用“一发多收”为接收端分配期望消息,以构成单播网络。该迫零方法首先根据接收端的干扰消息获取对应的零空间,再取多个零空间的交空间,最后将多个干扰消息同时置于对应的交空间中,即可实现在每个接收端同时迫零多个干扰消息。对于该多用户系统,分析得到了最优天线配置方案及系统复用增益的一般化结果。采用 Matlab对系统进行仿真分析,结果表明系统复用增益的理论值与仿真结果相一致。

Abstract: A new method of multi-user BC unicast and BC multicast coexistence was proposed,and a new method of zero-space interference was proposed.The main network of the model uses “loop mode” to allocate the expected message to the receiving end to form the multicast network.The secondary network uses the “one-over-one” to allocate the desired message to the receiving end to constitute an unicast network.The forcing zero method first obtains the corresponding zero space according to the interference message of the receiving end,and then takes a number of intersection space of zero space.Finally,multiple interference messages are placed in the corresponding intersection space at the same time,achieving more than one forcing zero interference message at each receiving end.For this multiuser system,the generalized results of optimized antenna configuration scheme and thereuse gain of the system are obtained.The system was simulated through Matlab.The results show that the theoretical value of the system reuse gain is consistent with the simulation results.
