Abstract

A novel method is proposed to get the adaptively optimized detection threshold of strong atmospheric turbulence channel model with K distributions, by estimating high-order accumulation of the covariance of received signal. Then performance of this adaptive signal threshold estimation method is tested and verified by Monte Carlo simulation, which shows that the threshold can be adaptively changed with the atmospheric turbulence channel conditions. Finally, the effectiveness of this method is verified by the actual measurement data under light rain, moderate rain and heavy rain. It is shown that the method proposed in this paper can effectively suppress the atmospheric turbulence and improve the performance of Free Space Optical communication system.
