  A closed-form non-line-of-sight (NLOS) turbulenceinduced fluctuation model is
derived for ultraviolet scattering communication (USC), which models the
received irradiance fluctuation by Meijer G function. Based on this model, we
investigate the error rates of the USC system in NLOS case using different
modulation techniques. Closed-form error rate results are derived by
integration of Meijer G function. Inspired by the decomposition of different
turbulence parameters, we use a series expansion of hypergeometric function and
obtain the error rate expressions by the sum of four infinite series. The
numerical results show that our error rate results are accurate in NLOS case.
We also study the relationship between the turbulence influence and NLOS
transceiver configurations. The numerical results show that when two-LOS link
formulates the same distance, the turbulence influence is the strongest for
long ranges and the weakest for short ranges.
