Paper Abstract

Non-line-of-sight (NLOS) optical scattering communication (OSC) is studied theoretically and experimentally. Making use of single scattering propagation model, properties of NLOS optical scattering channel are simulated numerically under some typical condition. The results show that the path loss of the channel is quite large, and becomes larger as apex angle of the transmitter and receiver increases. The results also show that the pulse transmitted from the source is broadened significantly after propagating in the NLOS optical scattering channel. It will limit the available bandwidth of the channel, and probably cause intersymbol interference in digital communication systems. Moreover, some elementary experimental facilities of NLOS UV communications are constructed. A UV digital communication system based on 254nm low pressure mercury lamp has been set up, and the BER of the system is about ~10-4 when the transmitter apex angle is 60 degree and bit rate is 1200bits/s. and NLOS light propagation experiments were conducted by exploiting a 370nm UV light-emitting diode (LED). With the progress of devices based on semiconductor in UV band, NLOS optical scattering communication with small volume and low power may be achieved in future.
