An adaptive optics correction arising from the sum of tilt, focus, astigmatism and coma components is applied to the bit error rate (BER) of M -ary pulse-position-modulated (PPM) oceanic optical wireless communication systems. The percentage reduction in BER is evaluated versus the oceanic turbulence parameters of the ratio of temperature to salinity contributions to the refractive index spectrum, the rate of dissipation of mean-squared temperature and that of kinetic energy per unit mass of fluid under different data bit rates, avalanche photodiode (APD) average current gains and the M values of the M -ary PPM. Our findings indicate that the percentage reduction in BER becomes larger when the ratio of temperature to salinity contributions to the refractive index spectrum or the rate of dissipation of mean-squared temperature or the data bit rate or the M value of the M -ary PPM is smaller, and when the rate of dissipation of kinetic energy per un...

自适应光学在M元脉冲位置调制海洋光无线通信系统误码率中的应用

由倾斜，聚焦，像散和彗差分量之和产生的自适应光学校正被应用于M进制脉冲位置调制（PPM）海洋光学无线通信系统的误码率（BER）。相对于海洋湍流参数评估了BER降低的百分比，该参数是温度与盐度比对折射率谱的影响，均方温度的耗散率以及在不同数据比特率下每单位质量流体的动能的耗散率，雪崩光电二极管（APD）的平均电流增益和Mary PPM的M值。
