There are many methods to improve the qualities of free optical communication (FSO) .It is one of the effective ways to improve anti-interference and noise faculty. Disadvantage factors and receiver background light in the laser communication result in interference. Noise is mostly in the receiver. The paper introduces in the FSO system, the laser signal which transmits in the atmosphere random channel is effected by atmosphere absorption, scattering, atmospheric turbulence and interference by the building sloshing; when received, it is effected by the ground light interference. Accordingly, we compare some proposed method with others. Based on the sources of noise, we detail the receiver noise and give some advices on designing photoelectric detective circuit. This study on FSO has a theoretical reference value.
