FD MU-MIMO Systems: Performance Analysis in the Presence of Imperfect CSI and Non-Ideal Transceivers
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.
