详细介绍基于OFDM的各种信道估计算法及其复杂度和适用性。(This application note gives an overview of the channel estimation strategies used in orthogonal frequency division multiplexing (OFDM) systems.)

Matlab中没有现成的Hermite插值函数，必须编写一个M文件实现插值。 设n个节点的数据以数组x0 （已知点的横坐标）， y0（函数值）， y1（导数值）输入（注意Matlat的数组下标从1开始）， m个插值点以数组x 输入，输出数组y 为m 个插值。编写一个名为hermite.m的M文件。 (Matlab is not off-the-shelf Hermite interpolation function, we must realize the preparation of a document M interpolation. N nodes for the data to an array x0 (known point of abscissa), y0 (function value), y1 (numerical derivative) input (note the subscript Matlat array starting at 1), m to the array of interpolation points x input and output array y for m months interpolation. Hermite.m the preparation of a M-file.)

生成指定概率分布的随机数，可用于数学与金融的随机分析(Specify the probability distribution of randomly generated number, can be used for the stochastic analysis and financial mathematics)

jacobi算法，看看能用不，我测试是能用的，希望大家也能用上！(jacobi algorithm, can not see, I can test, and I hope we all can be on!)

文中介绍了传统的PID控制原理，PID分为位置式和增量式，计算机控制是数字PID控制。一些 改进的PID控制算法是针对实际应用中的不足提出的，如积分分离式PID控制算法，抗 积分饱和算法，变速积分算法等，实际应用中，控制又分为简单PID控制和串级PID控 制，对一些典型的控制算法，选用典型控制对象用MArLAB软件进行了对应仿真。对仿 真结果进行了对比分析，说明了改进算法的作用。(This paper introduces the principle of the traditional PID control, PID into position and incremental, computer-controlled digital PID control. Some improvements in the PID control algorithm is less than the practical application of the proposed, such as discrete integral PID control algorithm, anti-integral saturation algorithm, changing integration algorithm and so on, practical application, the control is divided into a simple cascade PID control and PID control , for some typical control algorithm, selection of a typical control object MArLAB software with the corresponding simulation. The simulation results of comparative analysis carried out to illustrate the role of the improved algorithm.)
