Abstract

Based on the Monte Carlo (MC) method, a non-coplanar ultraviolet (UV) multiple-scatter propagation model with a height difference between the transmitter (Tx) and receiver (Rx) was presented. We focused on the relationship between bit error rate (BER) and the height difference between the Tx and Rx. We also studied the impact of the elevation angle and the off-axis angle of the Tx and Rx on the BER under the condition that the height difference is not zero. In addition, an outdoor UV communication testbed was set up to provide support for the validity of the MC model. The simulation results show that when the height difference between the Tx and Rx increases, the BER first decreases and then increases, the BER can be reduced by adjusting the transceiver elevation angle, and the bigger the off-axis angle is, the bigger BER is. The experimental results are in good agreement with the simulation results.
