Free-space optical transmission,Transmission impairments and their mitigations

We propose a phase measurement by fusing both the Gerchberg-Saxton algorithm and the model-based method. With simulation and experimental verification, the fusion method significantly improves the accuracy of phase measurement and the compensated received power.
