Samenvatting

Visible light communication (VLC) is a short-range optical wireless communication (OWC) utilizing white light-emitting diode (LED) lighting, so that the VLC systems can provide both illumination and communication. Multiple-input multiple-output (MIMO) is an attractive technology to efficiently improve the achievable rate of VLC with multiple LED luminaries which experience a low-pass effect in practical channels. In this paper, we investigate the performance of MIMO-VLC over three general low-pass channels, including exponential, first-order and Gaussian low-pass channels. Over frequency domain, two power loading strategies for multi-subcarrier orthogonal frequency division multiplexing (OFDM) are considered, namely uniform power loading and water-filling power loading. Expressions on the achievable rate to the corresponding link power budget and bandwidth are derived. Low-pass MIMO-OFDM VLC with a matrix channel decomposition has not extensively been treated theoretically in literature, to the best of our knowledge.

note = "Funding Information: separately compute fmax for each MIMO sub-channel. The development of a two-dimensional optimization is a theme for an extension of this paper. V. CONCLUSIONS We introduced a model for describing the achievable rate of MIMO-OFDM VLC systems over three common low-pass channels with uniform or water-filling power loading strategies, and we pointed out the importance of low-pass behavior for MIMO-OFDM VLC systems in an indoor environment. To the best of our knowledge, low-pass MIMO-OFDM VLC with a matrix channel decomposition has not extensively been treated theoretically in literature. Furthermore, the low-pass effect in practical MIMO-OFDM VLC channels will inevitably affect the data rate and quality of service in VLC systems, especially in a massive white LED luminaries scenario, which should be further investigated in future research.
