摘　　要：本文提出了一种在MIMO中继信道下，一对通信用户基于特征方向对齐预编码在两个通信时隙交换消息的传输方案。方向对齐的思想可以减少中继天线数目，提高信道容量并改善系统性能。而基于特征方向对齐的方案又避免了基于空间方向对齐的破零方案带来的功率损耗。同时，通过系统仿真，对比了该方案和现有破零预编码性能。In this paper, we study a new transmission scheme for one-pair user in two-way relaying channels based Eigen-direction alignment （ EDA ） .The alignment can reduce the number of antenna in relay, increase the capacity of the channel and improve the performance of the system.Meanwhile the EDA can optimize the significant power loss by using Zero-Force （ ZF ） .The performance of the proposed scheme is demonstrated by simulation results compared with ZF and MMSE scheme
