The Impact of Rain on Performance of Visible Light Communication

In this paper, a performance study of VLC communication channel impaired by rain, is presented. Our solution is based on software defined radio (SDR), LabVIEW and commercially available LED car taillights. This work focuses on performance testing of multistate QAM modulation formats throughout variable rain intensity and its influence on basic communication parameters (EVM, BER, transmit speed). This work will present our testing prototype, measured parameters and possible weak spots, which will be adjusted in future iterations.
