摘要	Atmospheric turbulence seriously degrades the performance of free space optical (FSO) communication systems, especially the coupling efficiency. In this paper, we propose a stochastic parallel gradient descent (SPGD) algorithm to compensate the atmospheric turbulence in FSO communication system. Theoretical analysis and work flow of the algorithm are given. Both simulation and experimental results indicate that the coupling efficiency can be increased from 12% to more than 80% after 270 iterations or more than threefold, which implies a significant improvement of the performance.
