Modeling of multi-channel MIMO-VLC systems in the indoor environment
The article presents a concept of simultaneous using multiple channels for data transmission (an approach MIMO- multiple input multiple output) in the visible light communication systems (VLC), which are considered here as their implementation inside buildings, in the aspect of their numerical modeling. There was presented both a mathematical description (a model) of such systems as well as obtained on this basis results in relation to the instances of MIMO-VLC system with two and four channels, respectively. The so-called non-imaging detectors were used at the receiver side . Obtained results allowed to gain a few valuable conclusions that were included in the last section of article.
