| Characterization of ultraviolet communication in a mixed aerosol environment |
|
| Abstract: |
| Wireless ultraviolet has strong scattering characteristics and can communicate through non-direct vision. When UV signals are transmitted in the atmosphere, they are affected by the absorption and scattering effects of atmospheric particles and atmospheric turbulence, resulting in attenuation of UV signal energy and reduced reliability of the communication system. This paper focuses on the channel model of UV non-direct-view single scattering communication, and simulates and analyzes the communication characteristics of UV light in atmospheric turbulence and mixed aerosol environment under horizontal, vertical and oblique range communication scenarios. The results show that the values of SNR, BER and channel capacity are smaller for rural and urban mixed aerosol communication than for horizontal and slant range communication in vertical communication scenarios with equal relative humidity. |
