Research on pulse response characteristics of wireless ultraviolet communication in mobile scene

Based on the Riemann sum method, we propose the idea of studying the pulse response width in a moving scene by using the non-line-of-sight (NLOS) wireless ultraviolet (UV) single-scatter communication model. We simulated the effect of the transmitter moving in eight directions from the origin on the pulse response width, when the receiver is fixed at point (100, 0, 0). Furthermore, the pulse response characteristics of the receiver were analyzed with varying elevation angle, beam angle, field-of-view (FOV) angle, and other geometric parameters. The results show that the pulse response width is widened under the condition of movement. In addition, the influence of the elevation angle of the transmitter on the pulse width is larger than that of the receiver. However, the effect of the FOV and beam angles on the pulse response width is not obvious when the FOV angle is large.
