多变量微分方程的PID控制程序，通过调整一个参数使得六个变量都的到控制(PID control procedures for multi-variable differential equations, by controlling a parameter makes the six variables are to control)

峰值信噪比（PSNR），一种评价图像的客观标准。水印提取判断效果。(Peak Signal to Noise Ratio (PSNR), objective criteria for evaluating image. Determine the effect of watermark extraction.)

电力线通信多径信道模型-Manfred Zimmermann模型，多径效应的传递函数H(f)可以用N条传输路径的叠加以及含有频率f、延时τ、距离d的方程来表示： H(f)=∑g_i *A(f,d_i )*e^(-j2πfτ_i ) 式中，i 为路径号， g_i为路径 i的加权系数(包含了传输系数和反射系数的作用)，A(f,d_i )为衰耗，其大小由长度、频率决定，τ_i是每条路径上的延时。 (Powerline Communication multipath channel model-Manfred Zimmermann model)
