Convolutional Coded On-Off Keying Free-Space Optical Links over Fading Channels
The performance of Free Space Optical (FSO) systems reduces due to the presence of turbulence and misalignment effects. In this paper, we investigate the error control coding schemes as a candidate solution to mitigate turbulence and misalignment induced fadings over free space optical links. we have investigated for first time the error performance for coded onoff keying (OOK) optical wireless...
متن کاملAtmospheric Channel Effects on Terrestrial Free Space Optical Communication Links
This paper illustrates the challenges imposed by the atmospheric channel on the design of a terrestrial laser communication link. The power loss due to scattering effect is described using the Kim/Kruse scattering model while the effect and the penalty imposed by atmospheric turbulence is highlighted by considering the bit error rate (BER) of an OnOff Keying modulated link in an optical Poisson...
متن کاملRate-Adaptive Free-Space Optical Links Over Atmospheric Turbulence and Misalignment Fading Channels
Atmospheric free-space optical (FSO) transmission using intensity modulation and direct detection (IM/DD) can provide high-speed links for a variety of applications, being an interesting alternative to consider for next generation broadband in order to support large bandwidth, unlicensed spectrum, excellent security, and quick and inexpensive setup [9]. Recently, the use of FSO transmission is ...
متن کاملImpact of atmospheric turbulence on free space optical (FSO) communication
In free-space optical communication links, atmospheric turbulence causes fluctuations in both the intensity and the phase of the received light signal, impairing link performance. Free Space Optical (FSO) communications is the only viable solution for creating a three-dimensional global communications grid of interconnected ground and airborne nodes. The huge amount of data exchange between sat...
متن کاملPacket testing in free-space optical communication links over water
NRL’s Chesapeake Bay lasercom test facility (LCTF) offers a variety of ranges for researching free-space optical laser communication (FSO lasercom) links in a maritime environment. This paper discusses link performance over the 16 km one-way range at the LCTF. There are several methods to determine the link quality in FSO lasercom. Bit-error-rate (BER) testing and packet testing are two possibl...
