中山大学sicily题库的一道题，解题思路明了，非常简单！(Sun Yat-sen University sicily exam a question, problem-solving Si Luming, very simple!)

模型预测控制中的预测控制，GPC的一种，还可以，希望有用(Model predictive control of predictive control, a GPC, and also, I hope useful)

IIR数字滤波器的特点是h(n)为无限长序列。设计的基本思想是：模拟系统与离散系统存在着互相模仿的理论基础，所以可以让数字滤波器的特性去模仿一个模拟滤波器的特性，得到数字滤波器的H(z)，H( )之间的变换关系。设计时，先设计一个模拟滤波器的传递函数 ，然后通过s变量与z变量之间的变换关系求出数字滤波器的系统函数H(z)。(IIR digital filter is characterized by h (n) for infinitely long sequence. The basic idea of the design are: analog systems and discrete systems there is the theoretical basis of mutual imitation, so you can make the characteristics of a digital filter to imitate the characteristics of an analog filters, digital filters are H (z), H () of the the relationship between the transformation. Design, first to design a simulation of the filter transfer function, s variables and z and then transform the relationship between variables derived digital filter system function H (z).)

无线衰落信道 在无线移动信道中，信号从发射天线经过复杂的传播环境到达接收天线，接收信号为各反射、衍射和散射分量以及信道噪声的复合，因而会产生严重的失真。另外，移动信道中由于移动台运动或信道环境的改变会使信道特性随时间随机变化，接收到的信号由于Doppler效应会产生更为严重的失真。 (OFDM has superior performance when transmitting high rate data in wireless fading channel.)
