Title
(ZH) 全双工MIMO中继器中的自干扰抑制
Abstract
(ZH)

在用于无线通信的中继器(300)中用于自干扰抑制的方法和设备,其中,中继器(300)布置用于接收从传送器(301)传送的信号<i>r</i>(<i>n</i>),以及用于将自干扰抑制的传送信号x<i>r</i>(<i>n</i>)传送到接收器(305)。通过确定(402)接收抑制滤波器矩阵W<i>r</i>?(302),确定中继器放大矩阵G?(303),以及确定(403)传送抑制滤波器矩阵W<i>t</i>?(304),然后应用抑制滤波器和放大器矩阵到接收信号<b>r</b>(<i>n</i>),实现自干扰抑制的传送信号x<i>r</i>(<i>n</i>)。
