摘　　要：In recent years,free space optical communication(FSO)has been a hot topic in satellite-to-ground communications,inter-satellite communications,and wireless access networks[1-4].It has the advantages of rich spectrum resources,no need for spectrum authorization,high spectrum efficiency verified by experiments,narrow beam angle,and low space loss under good weather.In point-to-point communications,the beam angle makes the FSO almost immune to multipath effects,and low-complexity Digital Signal Processing(DSP)algorithms can be used for recovery demodulation.
