The Analysis of Methods and Performance of Atmospheric Laser Communication Based on Polarization Shift Keying Modulation (PolSK) Technology

In the free space optical communication (FSO), the optical signals transmitted in the open air link .Inevitably, the signal received are influenced by atmosphere disturbance noise, so the reliability of FSO system is reduced. The present paper analyzed the principle of modulation and demodulation of PolSK and studied its main properties, then analyzed the performance of communication system by simulation experiments.
