DOI: 10.1109/lcomm.2018.2849079
Abstract: Load-modulated arrays (LMA) use a single central power amplifier (CPA) and tune (modulate) the antenna loads according to the information signal, eliminating the need for traditional RF chains (consisting of DACs, mixers, and filters) at… read more here.

DOI: 10.1109/lcomm.2019.2901685
Abstract: We study the minimum mean-squared error (MMSE) precoding for multiuser visible light communication downlink systems. Different from radio frequency systems, this problem does not admit a closed-form solution due to the light-emitting diode optical power… read more here.

DOI: 10.1109/lwc.2016.2642187
Abstract: In practical multiuser multiple-input multiple-output (MU-MIMO) systems with limited feedback, inter-user interference cannot be completely suppressed due to the channel state information quantization error, and the residual interference degrades the throughputs. In this letter, we… read more here.

DOI: 10.1109/tvt.2021.3131478
Abstract: Driven by the demand of building power-efficient next generation cellular systems, transmission schemes that facilitate the use of low-resolution digital-to-analog converters (DACs) have drawn great research attentions lately. In this correspondence, we investigated symbol-level precoding… read more here.
