Rate-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 کاملPairwise codeword error probability for coded free-space optical communication through atmospheric turbulence channels
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. In this paper, we describe several communication techniques to mitigate turbulence-induced intensity fluctuations, i.e., signal fading. These techniques are applicable in the regime in which the receiver aperture is s...
متن کاملConvolutional 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 کاملA Literature Survey on Performance of Free Space Optical Communication Links under Strong Turbulence
Free space optical communication is widely used for long range of distance operating under weak to strong turbulence conditions. In the existing method, many ideas have been proposed to analyze the performance of FSO links. To mitigate the effect of turbulence, error control codes and spatial diversity are used. This literature survey deals with the BER performance and turbulence effects on FSO...
متن کاملPerformance bounds for coded free-space optical communications through atmospheric turbulence channels
Error-control codes can help to mitigate atmospheric turbulence-induced signal fading in free-space optical communication links using intensity modulation/direct detection (IM/DD). Error performance bound analysis can yield simple analytical upper bounds or approximations to the bit-error probability. In this letter, we first derive an upper bound on the pairwise codeword-error probability for ...
