Abstract :
This paper presents an approximate closed-form model of non-line-of-sight (NLOS) ultraviolet (UV) single-scatter propagation in noncoplanar geometry for tractable analysis. The path loss is given as a function of the transceiver geometry settings and the optical properties of the atmosphere. Numerical examples on path loss show that the approximate model is consistent with the integral-form noncoplanar propagation model. Then, the data rate and the channel capacity of a quantum-limited receiver are further investigated with different parameters, such as bit error rate (BER), communication range, and transmitter optical power and off-axis angle.
