MultiUser Multiple-Input Multiple-Output (MU-MIMO) transmission scheme has drawn most attentions during the recent development of Long Term Evolution (LTE) systems. Based on the feedback information of the downlink channel, evolved NodeB may achieve multiple accesses via MIMO technology in MU-MIMO Transmission Mode and allow user equipments to share resources in frequency and time domain. In this paper, the authors review several signal detectors and evaluate their performance in MU-MIMO transmission. This paper aims at the feasibility study of receivers in LTE systems. Different scenarios have been considered in the evaluation progress, e.g., low and high spatial correlation, real channel estimation and feedback delay.
