Abstract

Abstract

To prove the reciprocity of an atmospheric turbulent channel in bidirectional optical transmission systems, we propose a method for measuring the correlation between the fading of instantaneously received signals and establish a mathematical model for analyzing the measurement data. Experiments of bidirectional optical transmission measurements were carried out between two tall buildings separated by 883 m. According to the measured speckle image data, we verified the instantaneous-fading correlation of the channel and analyzed the effect of the normalized received signal fluctuation variance on the correlation coefficient in practical scenarios. It was shown that most of the instantaneous-fading correlation coefficients of optical channels in the two counter-directions were above 0.85 and even up to 0.95, which proves that reciprocity can be well maintained for a bidirectional turbulent optical channel. With an increasing fluctuation variance of the normalized received optical signal, the correlation coefficient is slightly descending.
