A Minimum Jamming Precoding Algorithm and Its Performance Analysis for the Downlink Multiuser System

  • 摘要: 该文针对多天线多用户系统的下行链路,提出了一种基于最小拥塞准则的线性预编码算法,并且利用非线性规划理论推导出了其相应最优发射权值的闭式表达式。这种算法通过最小化期望用户对其他用户的干扰,可以在保证一定性能的基础上,有效地降低系统的复杂度。此外,由于该系统为干扰受限,所以文中还考察了其信干比性能,并利用前边得到的闭式解推导出了其分布的概率密度函数,从而给后续的分析和应用带来了方便。
