Abstract
In this article the author’s team deals with problems of modulation formats for Free Space Optical (FSO) Communications. FSO communications have high bandwidth, low signal attenuation, quick installation, security, unlicensed band and low cost. In FSO communication occurs due to the influence of atmospheric effect (attenuation, and fluctuation the received power signal, influence turbulence). Here will be dealing modulation schemes OOK (On-Off keying) and Subcarrier Intensity Modulation (SIM) based on a BPSK (Binary Phase Shift Keying). In which will studied their characteristic and effect of atmospheric influence on the received signal. This results in decreased Eye-Diagram, Signal-to-Noise Ratio (SNR) and Bit Error Rate (BER). To evaluate the modulation formats in atmospheric turbulence is used simulation box with heat and wind sources.
