In this Letter, closed-form expressions of ergodic capacity, outage probability, and outage rate are derived for an atmospheric optical communication link using intensity modulation and direct detection with unbounded optical wavefront propagating through a homogeneous and isotropic turbulent medium. The optical scintillation of the received signal is modeled with the recently proposed Málaga or M turbulence distribution. By taking advantage of this unifying statistical model, the expressions here presented are valid for all possible irradiance fluctuation conditions, leading to direct relationships between turbulence parameters and link capacity performance.
在这封信中,推导出了使用强度调制和直接检测的非定常容量、中断概率和中断速率的闭式表达式,用于通过均匀各向同性湍流介质传播的无限光前的大气光通信链路。接收信号的光闪烁用最近提出的马拉加或 M 湍流分布进行建模。利用这个统一的统计模型,这里提出的表达式对于所有可能的辐照度波动条件都是有效的,从而导致了湍流参数与链路容量性能之间的直接关系。
