To mitigate the influence of the atmosphere turbulence, we proposed a new method base orthogonal phase modulation with self homodyne detect. This method can not only mitigate the influence of the turbulence, but also adjust the communication date rate steplessly. The experiment results show that the method is very suitable to the satellite-to-ground link.
