Free-Space Optical Communications Using on–off Keying and Source Information Transformation


Free-space optical Communication using on–off keying (OOK) and source info transformation is proposed. It's shown that the source data transformation allows the proposed system to detect the OOK signal without requiring the knowledge of instantaneous channel state data and the probability density function (pdf) of the turbulence model. Analytical expressions are derived for the pdf of the detection threshold, and an upper sure is obtained on the average bit error rate (BER). Numerical studies show that the proposed system can achieve comparable performance to the idealized adaptive detection system, with a greatly reduced level of implementation complexity and a symptom-to-noise ratio performance loss of solely dB at a BER of for a lognormal turbulence channel with .
