| The article presents the concept solution of two main issues of visible light communication systems, i.e. the lack of a cost-effective feedback channel and the handling of high throughput. The concept is based on merging of the multiple input multiple output approach, well-known from radio transmission domain, with using of LEDs in a double role, i.e. both as emitters and detectors of light. The feasibility of the proposal was confirmed by the results of the research, carried out for two-channel system of this type. |
