Abstract
Employing unmanned aerial vehicle (UAV) in fiber-based visible light communication (FVLC) can not only enhance the flexibility of visible light communication, but also provide users with sufficient lighting conditions. In the downlink UAV-assisted FVLC (UFVLC) system based on power domain non-orthogonal multiple access (PD-NOMA), the outdoor weak-turbulence channel environment is considered in this paper, where the UAV is set as a communication relay. We have analysed the distribution function of received signal and system noise in the actual environment, derived the calculation formulas of noise and signal-to-noise ratio (SNR). The theoretical bit error rate (BER) expression of the UFVLC system is derived by analysing the influence of UAV and receiver position. Moreover, numerical results demonstrate that the theoretical analysis is consistent with the simulation results, especially in the case of high SNR.Keywords
