Ekvalizace optického vysílače pro komunikaci viditelným světlem

Abstract

This bachelor thesis deals with the issue of visible light communication (VLC), specifically by equalizing the optical transmitter for VLC. In the first chapters, this technology is described from history through basic principles to individual components as light sources and detectors. There are also some modulations described in IEEE 802.15.7. The rest of the work is focused to measuring the bandwidth of the optical transmitter, designing the circuit for equalizing using the data from the measurement and subsequently testing the transmission parameters with the used equalizer.
