摘要

    摘要
  • 摘要: 自由空间光通信在未来全球通信网中具有潜在的应用价值，然而自由空间光通信的性能易受大气湍流影响，而自适应光学能够解决大气湍流问题。在gammagamma分布大气湍流中，用自适应光学技术对自由空间光通信系统进行补偿，进行通信系统误码率的分析，给出了上行链路和下行链路的模拟结果。结果表明：自适应光学误差补偿技术能够很好地提高自由空间光通信的性能，并且低阶自适应光学补偿就能达到很好的校正效果。
    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.
