This article aims for meeting with influences of the atmosphere on real professional Free-Space Optical (FSO) link. Atmospheric effects could cause a degradation of quality of FSO communication and of received optical beam in shape of decreasing of optical power value through parameter RSSI (Received Signal Strength Indicator). Finally, this could even lead to communication loss. The article focuses...
This article presents the concept of deploying Software Defined Radio (SDR) for laser beam modulation in Optical Wireless Communication (OWC). To achieve modulation and demodulation of the beam generated by Laser Diodes (LDs). SDR is used to provide a sophisticated and flexible possibility of readjustment without deeper intervention into the electronics of the OWC connection. To make conclusions regarding...
This article is focused on the atmospheric turbulences and their effect on optical beam. The Free Space Optics link with atmospheric turbulences was created in software OptiSystem. The results given by software are compared with Andrews's method. Free Space Optics link worked at wavelengths 850 nm and 1550 nm.
