Abstract

Aiming to solve the problems of the atmospheric turbulence in free-space optical communications which cause the increase of the system bit error and influence the communication stability, an algorithm is proposed to suppress the influence of atmospheric turbulence. This algorithm combines traditional grouped matrix interleaver and random interleaver design methods to construct a new type of interleaving matrix to solve the turbulence effect under different atmospheric conditions. A field programmable gate array (FPGA) board with external DDR3 is used to implement the algorithm and optimize the delay. The results show that the algorithm is accurate and reliable in different turbulence models. At the same time, the impact of turbulence effects on link performance can be reduced to a certain extent.
