说明：  基于matlab中的simulink搭建的雷达信号处理仿真平台(based on Matlab Simulink structures of the radar signal processing simulation platform)

实现了三级小波变换数字水印嵌入中频小波信号，要求图像大小256*256RGB，水印图片大小32*32二值图像。(Three wavelet transform digital watermarking embedded the IF wavelet signal to the image size 256* 256RGB watermark image size 32* 32 binary image.)

先做灰階圖片，再利用IMHIST來做統計，在做SMOOTH來讓使用者更容易了解圖片的特色 (Grayscale images do first, and then use IMHIST do statistics, SMOOTH do to make it easier for users to understand the characteristics of the picture)

搭建的双馈风力发电机变流器控制模型，我自己做项目的时候用过，效果很好，大家可以随便用。 (Converter control model of doubly-fed wind power generator, I was working as a project, the effect is very good, you can literally use. )

电机的机械特性图，由matlab计算以及仿真得到(Mechanical characteristics of the motor map, as well as by the matlab simulation has been calculated)

若不希望用与估计输入信号矢量有关的相关矩阵来加快LMS算法的收敛速度，那么可用变步长方法来缩短其自适应收敛过程，其中一个主要的方法是归一化LMS算法（NLMS算法），变步长 的更新公式可写成 W（n+1）=w（n）+ e（n）x（n） =w（n）+ （3.1） 式中， = e（n）x（n）表示滤波权矢量迭代更新的调整量。为了达到快速收敛的目的，必须合适的选择变步长 的值，一个可能策略是尽可能多地减少瞬时平方误差，即用瞬时平方误差作为均方误差的MSE简单估计，这也是LMS算法的基本思想。 (Want to estimate if the input signal vector and the relevant matrix to speed up the convergence rate of LMS algorithm, then the variable step size method can be used to shorten its adaptive convergence process, one of the main method is normalized LMS algorithm (NLMS algorithm) , variable step-size update formula can be written W (n+ 1) = w (n)+ e (n) x (n) = w (n)+ (3.1) where, = e (n) x (n) the right to express filter update vector iterative adjust the volume. In order to achieve the purpose of fast convergence, we must choose the appropriate value of variable step size, a possible strategy is as much as possible to reduce the instantaneous squared error, which uses the instantaneous squared error as the mean square error MSE of the simple estimate, which is the basic LMS algorithm思想.)

This source code describes the OFDM transmitted waveform at the transmitter both in frequency as well as time domain

该源码实现了基本的目标检测方面的功能。如肤色检测、卡尔曼滤波、降噪、人脸识别等等。(The source code to achieve the basic function of target detection. Such as skin color detection, Kalman filtering, noise reduction, face recognition and so on.)

Most books that use MATLAB are aimed at readers who know how to program. This book is for people who have never programmed before.
