在这篇文章中，我们提出了一个数字滤波器的设计方法，抑制自干扰产生的单频全双工无线中继，也补偿从源站到中继站的频率选择性衰落。信号和无线中继系统可以分别建模为随机过程和离散时间线性时不变系统。我们制定的最小均方误差（MMSE）标准的基础上的滤波器设计问题。结果表明，滤波器的设计问题是一个H最优控制问题。仿真结果表明了该方法的有效性。
In this article, we propose a design method of a digital filter that suppresses self-interference arising at a singlefrequency full-duplex wireless relay, and also compensates frequency selective fading from a source station to the relay station. The signals and the wireless relaying system can be modeled as random processes and a discrete-time linear time-invariant system respectively. We formulate the filter design problem based on the minimum-mean-square error (MMSE) criterion. It is shown that the filter design problem is equal to an H optimal control problem. The effectiveness of the proposed method is shown by simulations.
