线性调频信号是一种雷达常用的电磁波信号，当雷达信号检测到目标时候，反射后得到雷达回波信号(LFM signal is a kind of radar used electromagnetic signals, when the radar signal detection to the target, the reflection of radar echo signal after)

本书着重介绍MATLAB在工程数据数学处理中应用的基础知识和计算方式，其内容涉及MATLAB主包和部分工具箱内容。本书另外涉及MATLAB系统的模糊逻辑工具箱的自适应神经网络模糊推理系统，对自适应神经网络模糊推理系统的数学原理、功能使用和程序调用进行了较详细的论述。(This book focuses on MATLAB mathematical treatment in the application of engineering data, the basic knowledge and methods of calculation, involving the main package and part of the MATLAB toolbox contents. This book also involve MATLAB Fuzzy Logic toolbox of adaptive neural network fuzzy inference system, adaptive neural network on the mathematical theory of fuzzy inference system, functions and procedures call for using a more detailed discussion.)

采用MFCC算法提取出能表征信号本质特征信号的参数，进一步对信号进行分类研究作准备(describle the MFCC feturae)

OFDM系统仿真函数，可用于信道估计以及物理层安全领域(OFDM system simulation functions for channel estimation and physical layer security field)

说明：  产生正弦波、均匀白噪声、高斯白噪声图形；利用小波变换去噪并求信噪比。(Sine wave, uniform white noise and Gauss white noise are generated; wavelet transform is used to denoise and SNR is calculated.)

带simth补偿的pid控制器主要用于纯滞后系统的pid温度控制，属于改进型的pid控制器。本simulink仿真为毕业设计内容，运行效果良好。本例设定温度200度，参数之类可以根据需要自由修改(Smith compensation with pid controller mainly used for pure delay systems pid temperature control, are improved pid controller. The simulink simulation content for the graduation project, run well. In this case temperature of 200 degrees, like the parameters can be modified according to need freedom)
