The results show that the obscuring ratio has obvious influence on the beam spreading in weakturbulence.
结果表明,对于均强聚焦光束湍流大气传输,在弱湍流效应条件下,光斑扩展受遮拦比影响较大;

The bit error ratio (BER) of the system over weakturbulence based on adaptive filter is below 10 ~ (-8), which can satisfy the communication requirement.
