Abstract

This work outlines a framework for full-duplex (FD) multiple-input multiple-output (MIMO) communication systems considering practical conditions, such as imperfect channel state information (CSI) and hardware impairments (HWIs). We analyze the performance of FD multi-user (MU) MIMO systems, specifically studying the effects of practical channel estimation errors and HWIs on the spectral efficiency (SE) performance of FD MU-MIMO systems. Maximum ratio combining/maximum ratio transmission (MRC/MRT) and zero-forcing reception/zero-forcing transmission (ZFR/ZFT) linear detectors/precoders are considered at the base station (BS). Moreover, linear minimum mean square error (LMMSE) and least square (LS) error estimation are used to estimate the channel at the BS. Mathematical derivations for the lower bounds of uplink (UL) and downlink (DL) SEs are presented in the context of imperfect CSI and HWIs. Computer simulations validate the analytical derivations. The results demonstrate the tightness of the obtained bounds.

FD MU-MIMO 系统:不完美 CSI 和非理想收发器情况下的性能分析
本工作概述了一个考虑实际条件的全双工(FD)多输入多输出(MIMO)通信系统框架,例如不完善的信道状态信息(CSI)和硬件损伤(hwi)。分析了FD多用户(MU) MIMO系统的性能,具体研究了实际信道估计误差和hwi对FD MU-MIMO系统频谱效率(SE)性能的影响。最大比值组合/最大比值传输(MRC/MRT)和零强迫接收/零强迫传输(ZFR/ZFT)线性检测器/预编码器在基站(BS)中被考虑。此外,采用线性最小均方误差(LMMSE)和最小二乘误差(LS)估计信道。在不完全CSI和不完全hwi的情况下,给出了上行(UL)和下行(DL) se下界的数学推导。计算机模拟验证了解析推导。结果表明所得到的边界是严密的。
