Abstract :
As the range of the non-line-of-sight (NLOS) ultraviolet (UV) communication increases, atmospheric turbulence will become one of the primary atmospheric processes that affect the propagation of optical waves besides atmospheric absorption and scattering. This paper analyzes scintillation attenuation (SA), indicating that it should not be ignored for long communication range and relatively strong turbulence. A turbulence model considering SA is proposed, and the marginal probability density function (PDF) of the received optical power is derived. Then, the signal-to-noise ratio (SNR) and the bit-error-rate (BER) of NLOS UV communication systems are analyzed, showing that atmospheric turbulence induces greater performance deteriorations due to SA.
