摘要

Visible light communication (VLC), which can synergistically provide both illumination and data transmission, is garnering increasing attention. Dimming support is one of the main challenges for VLC systems. Under the requirements of the uniformity illuminance ratio (UIR) according to lighting engineers and the indoor illuminance range standardized by the international organization for standardization (ISO), an antenna selection based dimming (ASD) scheme is proposed for multiple-input multiple-output (MIMO) VLC systems equipped with multiple lamps. By fully taking advantage of the available channel state information (CSI) at both the transmitters and the receivers, the proposed scheme can select the best subset of light-emitting diodes (LEDs) from the lamps. To the best of the author's knowledge, this is the first design of a dimming scheme specially for MIMO-VLC systems with considering the UIR as well as the indoor illuminance range. Simulation results verify that the proposed ASD scheme has significant bit error ratio (BER) performance gains over the conventional dimming scheme for various dimming proportions and receiving positions, which makes it a more promising alternative dimming scheme for MIMO-VLC systems.
