In this paper, we address antenna selection (AS)-aided massive multi-user multiple-input-multiple-output (MU-MIMO).system based on maximum signal-to-noise ratio, where imperfect channel state information (CSI), time-varying channel and.antenna spatial correlation are considered. More explicitly, a computationally simple training-based channel estimator (CE) is.firstly employed for obtaining the imperfect down-link CSI. Channel quantization (CQ) is subsequently introduced by the feedback.link whi
