Abstract
In free space optical (FSO) communication, atmospheric
turbulence causes fluctuation in both intensity and phase of the received
light signal what may seriously impair the link performance. Additionally,
turbulent inhomogeneities may produce optical pulse spreading. In this
paper, a simple rate adaptive transmission technique based on the use of
variable silence periods and on-off keying (OOK) formats with memory
is presented. This technique was previously proposed in indoor unguided
optical links by the authors with very good performance. Such transmission
scheme is now extensively analyzed in terms of burst error rate, and
shown in this paper as an excellent alternative compared with the classical
scheme based on repetition coding and pulse-position modulation (PPM),
presenting a greater robustness to adverse conditions of turbulence.
