系统辨识教材，个人认为很不错，希望对大家有用！(The system identification teaching material, I believe is very good, hoped that is useful to everybody!)

本文档是基于matlab的OFDM源程序，包括卷积码编码，交织，加导频等。(This document is based on the OFDM matlab source, including convolution coding, interleaving, plus the pilot and the like.)

Consider generating 64 samples of a sinusoidal signal of frequency 1KHz, with a sampling frequency of 8KHz.

说明：  螺旋扫描区域全覆盖算法，区别以往算法，极大程度优化路径规划。(Spiral scanning region full coverage algorithm)

一是利用计算机对正整数进行素因子分解认识素数，通过运用筛法与试除法寻找一定范围内的素数，体会到筛法比试除法有效但无法找出所有素数；二是通过若干特殊形式的素数的研究，寻找素数生成公式，发现一些结论；三是借助于非线性拟合技术，观察素数分布规律，利用其研究有关数论问题。(The first computer was used to prime factor decomposition of positive integers understanding of prime numbers, through the use of screening method and trial division to find prime numbers within a certain range, the division experienced a test of an effective screening method but can not identify all the prime numbers second is through a number of special form of prime numbers research, looking for prime number generation formula, found that some of the conclusions third, by means of non-linear fitting technique to observe the distribution of prime numbers, using their research on number theory problems.)

系统讲述了matlab在数学建模中的应用，有助于良好的掌握matlab的工具箱使用和进一步了解matlab的强大功能。(Matlab system described in the application of mathematical modeling to help a good grasp of the matlab toolbox to learn more about the use and power of matlab.)

说明：  这是现代信号处理领域最常用的信号分析方法！(this modern signal processing is the most commonly used method of signal analysis!)
