PDradar_signal_processing

this are the example codes from control system engineering from NORMAN NISE

可以求解系统的亚谐波共振,例如求解轧机振动系统的1/3亚谐波共振(You can solve the sub-harmonic resonance system)

P Delta FEM Analysis

说明：  传感器阵列波束优化设计与应用书籍第7章的matlab程序(Chapter 7 matlab program of book Sensor array beam optimization design and application)

文档中介绍了matlab数值分析的方法，并且有一些实例。(The document describes the method of numerical analysis matlab, and there are some examples.)

这个是一个比较基础的东西，比较适合初学者来学习，同时，最小二乘法是一个很不错的拟合方法(two priority methods-least logarithm square method)

一维连续小波变换，多尺度分解，系数图形显示，不同尺度的重构。(One-dimensional continuous wavelet transform, multi-scale decomposition coefficient graphical display, the reconstruction of the different scales.)

低通滤波器，对数据进行平滑，也叫做最小二乘法，Savitzky-Golay算法(a particular type of low-pass filter, well-adapted for data smoothing, and termed variously Savitzky-Golay, least-squares, or DISPO (Digital Smoothing Polynomial) filters. Rather than having their properties defined in the Fourier domain and then translated to the time domain, Savitzky-Golay filters derive directly from a particular formulation of the data smoothing problem in the time domain)

实现滤波器的功能，从而使有噪声的图像得以修复。(Realization of the filter function, so there is noise in the image can be repaired.)

MATLAB在通信系统仿真中的应用，包括有通信仿真的一半步骤,通信系统模型及仿真实例.(communication systems in MATLAB simulation applications, including communication simulation half steps communication system model and simulation results.)
