自由空间光通信系统在大气湍流信道下的3个主要性能指标分析，即平均误码率、中断概率和平均信道容量。其中大气湍流采用gamma-gamma湍流信道衰退模型。3个M文件为平均误码率与平均信噪比之间的关系(BER_SNR.m)，中断概率(OutageP.m)，以及平均信道容量与平均信噪比之间的关系（C_SNR.m）。程序可直接运行。(The analysis of 3 key performance indicators of Free-Space Optical communication system in atmospheric turbulent channel, namely the average bit error rate, outage probability and the average channel capacity. The atmospheric turbulence is modeled by the gamma-gamma turbulent channel fading model. Three M-files are the relationship between the average bit error rate and the the average SNR (BER_SNR.m), outage probability (OutageP.m), the relationship between the average channel capacity and the average SNR (C_SNR.m).The programs can run directly.)

说明：  演变过程 自抗扰控制器自PID控制器演变过来，采取了PID误差反馈控制的核心理念。传统PID控制直接引取输出于参考输入做差作为控制信号，导致出现响应快速性与超调性的矛盾出现。(In the process of evolution, ADRC evolves from PID controller and adopts the core idea of PID error feedback control. Traditional PID control directly draws the output from the reference input as a control signal, which leads to the contradiction between response speed and overshoot.)

根据)EF 特性中的对比度敏感度， 即空间频率特性曲线，对图像进行二维多级小波分解，由分解后的各小波分量，提取各频段相应的亮 度、清晰度和相关度指标；然后将这三个指标的几何平均与频段加权系数的内积做算术平均，以此作 为图像质量的综合评价指标(According to) EF characteristic of contrast sensitivity, that is spatial frequency characteristic curve, the image is two-dimensional multi-level wavelet decomposition, the decomposition of the wavelet component, extract the frequency band corresponding brightness, clarity and relevance of indicators then the geometric mean of these three indices and the band doing weighted coefficient of the arithmetic mean within the product as a comprehensive evaluation of image quality index)
