5 Conclusions
This paper addressed the designs of joint linear transceivers with improper constellations for SU-MIMO systems. Specifically, it made the following important extensions to the previous designs: (i) Obtaining a joint linear transceiver for SU-MIMO systems under perfect CSI assumption and with improper modulations, and (ii) Obtaining a joint linear transceiver for SU-MIMO systems under imperfect CSI assumption and with improper modulations. In both cases, the transceiver designs are accomplished with an iterative procedure, which typically converges in 4 to 6 iterations. Performance advantage of the proposed designs in terms of the system’s BER was thoroughly demonstrated with simulation results. Finally, it is pointed out that the design proposed in this work can be extended to the multi-user MIMO (MU-MIMO) systems.

MIMO系统的非线性调制收发器设计
摘要
本文是基于单用户多输入多输出系统,采用一系列的如二进制相移键控和多进制振幅键控(M-ASK),提出一种新的非线性联合收发器,最大限度地减少了解码器输出端的总均方误差。非线性联合收发器设计在两种情况进行了讨论,对于完美的信道状态信息 (CSI),此设计在发射端和接收端进行了完善。对于不完美信道状态的情况,该模型考虑到两个信道传输和接收的相关性,以及信道估计的误差。该收发器的
