    • Abstract
  • Free space optical communications have potential applications in the future global communication network. However, performance of free space optical communication is degraded by atmospheric turbulence. Adaptive optics technique can be used to solve this problem of turbulent atmosphere. In this paper, the performance of communication system through gamma-gamma atmospheric turbulence using adaptive optics was analyzed; the simulation results of laser uplink and downlink propagation were presented. The results indicate that the performance can be improved significantly using adaptive optics error compensation technique, and low-order Zernike mode compensation can have good correction.
