摘要翻译：
基于Tomlinson Harashima(TH)预编码的双向中继网络的非线性收发信机大多采用完全信道状态信息(CSI)。本文提出了一种新的鲁棒的TH预编码方案，适用于收发信机和中继节点都有多个天线的双向中继网络。我们假设不完全CSI，并且信道不确定性被一个球形区域所限定。此外，我们考虑均方误差之和作为目标函数，在有限的功率约束下，收发器和中继节点。通过仿真来评估该方案的性能，并验证该方案的有效性。

英文摘要：
Most of the non-linear transceivers, which are based on Tomlinson Harashima (TH) precoding and have been proposed in the literature for two-way relay networks, assume perfect channel state information (CSI). In this paper, we propose a novel and robust TH precoding scheme for two-way relay networks with multiple antennas at the transceiver and the relay nodes. We assume imperfect CSI and that the channel uncertainty is bounded by a spherical region. Furthermore, we consider the sum of the mean square error as the objective function, under a limited power constraint for transceiver and relay nodes. Simulations are provided to evaluate the performance and to validate the efficiency of the proposed scheme.
