Experimentální ověření vlivu atmosférických a mechanických jevů na komunikaci V2V a V2I pomocí technologie VLC–OFDM na bázi SDR

Abstract

The work studies the visible lighting communication (VLC) during which the OFDM technique was used. It evaluates the influence of carrier frequency, bandwidth and M-QAM modulation based on the results obtained from measurements. During channel parameter testing, the detector was positioned at different distances and horizontal offset to the transmitter. Measurements took place under laboratory conditions as well as outdoors when it evaluates the influence of the sun on communication. In addition, wireless data transmission has been exposed to atmospheric phenomena such as rain and fog that have been suitably simulated in laboratory conditions. The contribution of this work is to set limits of parameters of communication channel in various positions and phenomena that influence communication in real time.
