Abstract
Line-of-sight optical communication channels are characterized by the high data rate, but they cannot provide stable data transmission in the presence of obstacles in the communication line. Non-line-of-sight (NLOS) optical communication is free of this shortcoming and can be multicast. We have created an optical-electronic system for NLOS communication at a wavelength λ=850 nm. It is shown that in the evening, NLOS communication is possible at a baseline distance of 75 m and receiver azimuth angles 0-40° with the symbol error rate no higher than 0.009. At a baseline distance of 1300 m and receiver azimuth angles of 0 5°, NLOS communication with the symbol error rate no higher than 0.236 is possible.
