摘要
摘要:该文考虑一个大规模MIMO全双工中继系统，该系统下多个单天线的源节点和多个单天线的目的节点通过一个在接收端和发送端分别配置${N_{{\mathop{\rm rx}\nolimits} }}$和${N_{{\mathop{\rm tx}\nolimits} }}$根天线的中继进行通信。在非完美信道状态信息(CSI)和硬件损害的情况下，中继端在译码转发(DF)的方式下使用迫零(ZF)方法去处理接收信号和发送信号，并获得了闭合形式的接收速率表达式。根据这些表达式，可以得到各种功率收缩规律，发现随着中继端接收天线数量和发送天线数量以一定比例趋近于无穷大时，源节点的能量、中继端的能量和导频的能量可以以一定条件收缩来维持系统性能。

Abstract:A massive MIMO full-duplex relaying system is considerd in this paper, in which multiple single-antenna sources simultaneously communicate with multiple single-antenna destinations using a single relay that is equipped with ${N_{{\mathop{\rm rx}\nolimits} }}$ receive antennas and ${N_{{\mathop{\rm tx}\nolimits} }}$ transmit antennas. Under imperfect Channel State Information (CSI) and hardware impairment, the relay processes the received and transmitted signals by means of Zero-Forcing (ZF) and uses Decode-and-Forward (DF) scheme. The closed-form expressions of achievable rate are deduced. Based on these expressions, the various power scaling laws can be obtained. It is shown that when the two numbers of the relay receive and transmit antennas go to infinity but with a fixed ratio, the system can maintain a desirable quality of service in the case of scaling the transmit powers of the sources, relay and pilots.
