Abstract :
The beam reshaping method is adopted for improving the efficiency in the non-line-of-sight (NLOS) ultraviolet scattering communication channel. By photon-tracing Monte Carlo simulation, the numerical results show the beam with rectangular or elliptical photometries has significant advantage in the received signal intensity against the circular one. The influences of the geometric configurations of both the transmitter and the receiver on the received signal intensity are discussed. The corresponding impulse responses are also analyzed.
