我们研究了一个基于均方误差的线性收发器的设计问题，在一个多输入多输出的蜂窝系统与全双工基站服务多个半双工的上行链路和下行链路用户同时在实际的每个天线的功率约束。首先，提出了一种迭代非线性高斯-赛德尔型算法更新波束形成器的每个发射天线使用简单的封闭形式的表达式。在此基础上，提出了一种基于交替方向乘法器的低复杂度设计方法。
We study a mean-squared-error-based linear transceiver design problem in a multiple-input multiple-output cellular system with a full-duplex base station serving multiple half-duplex uplink and downlink users simultaneously under the practical per-antenna power constraints. First, an iterative nonlinear Gauss-Seidel type algorithm updating the beamformer of each transmit antenna using simple closed-form expressions is proposed. Then, a lower complexity design is proposed based on alternating direction method of multipliers.
