Abstract
Instead of suppressing multiuser interference as a harmful element by conventional precoders, constructive interference (CI) technique is able to exploit multiuser interference as a beneficial element for enhancing receiver performance. This paper is the first work investigating the feasibility of CI in multiuser multiple-input and multiple-output (MIMO) systems. A joint CI based combiner and precoder approach is proposed, and then a robust design is further developed taking into consideration of imperfect channel state information (CSI). Simulation shows that the proposed designs significantly outperform the existing benchmarks, and shows a high level of robustness against CSI error.
