说明：  给定入射信号角度分别为 -22度 ，6度，18度时，不同信噪比情况下各种空间谱估计算法得到的曲线图(given incident signals point to-22 degrees, 6 degrees, 18 degrees, the signal to noise ratio under different space spectral estimation algorithm of the curve)

本文件里面有几个基于MUSIC算法的DOA估计。可以帮助新手熟悉过程。(Based on this document, there are several MUSIC DOA estimation algorithm. You can help the novice familiar with the proces)

数字控制系统是一种以数字计算机为控制器去控制具有连续工作状态的被控对象的闭环控制系统。因此，数字控制系统包括工作于离散状态下的数字计算机和工作于连续状态下的被控对象两大部分。我的课题的数字部分（PID）仿真由相应的离散传函实现，运用数字PID对被控对象实行准确控制。通过调节比例（P）、积分（I）、微分（D），使对象的输出达到预期的效果。(Digital control system is a kind of digital computer for the controller to control a continuous state of the object and closed loop control system. Therefore, the digital control system, including work on the discrete state of the digital computer and work in a continuous state of the plant is two parts. My topic of digital section (PID) simulation by the realization of the corresponding discrete transfer function using the digital PID control of the plant is implemented accurately. By adjusting the ratio of (P), integral (I), differential (D), so that the output of the object to achieve the desired results.)

产生16路信号，画出16路原始信号的频谱叠加图以及滤波器响应，并画出结果信号的时域和频域波形(Generate 16-channel signal, draw 16 original signal spectrum overlay and a filter response, and draw result signals in time domain and frequency domain waveforms)

广义似然比检测，单脉冲雷达波束内的多个不可分辨目标(Generalized likelihood ratio testing multiple single pulse radar beam can not distinguish target)

image encrypted watermarking using LSB

说明：  该代码可用于计算脑电信号的小波熵，方便灵活。(wavelet entropy for eeg)

基于边缘梯度的图像匹配，实现对寻找块图像的精确寻找(Gradient based edge image matching, to achieve the exact image of the search block to find)

matlab的编程书籍。。强烈推荐。。。。(matlab programming books. . Highly recommended. . . .)
