Atmospheric laser communication system on polarization shift keying(Polarization shift keying,referred to as PolSK)is a new technique in atmospheric laser communication technology,laser communication system using PolSK modulation mode is not affected by the source phase noise and quantum limited noise,namely the use of vector properties of light,digital information can be encoded into the polarization state of light signal,with different polarization states to express the logic signal 0 and 1,to realize the information transmission.This modulation mode can suppress the nonlinear optical effect,applicable to multilevel modulation,can reduce background noise,to improve the laser signal detection signal-to-noise ratio,reduce the communication error rate,enhance the reliability of the communication system and anti-interference ability,high bit rate transmission
