MATLAB DCT该案例给出了一个水印源程序代码 ，可以此为参考作进一步开发(MATLAB DCT水印源程序代码)

Chapter 2 DSP course

DTMF(双音多频)是用两个特定的单音频组合信号来代表数字信号的一种编码技术。两个单音的频率不同，代表的数字或实现的功能也不同。可采用8种频率代表电话机上的16个按键，10个数字键0~9和6个功能键*、#、A、B、C、D。具体的频率组合见参考书。要求： (1) 根据键盘输入的符号，利用MATLAB产生对应的DTMF信号；(2) 分别利用FFT算法和Goertzel算法计算该DTMF信号的频谱并画出频谱图；(3) 根据频谱图确定DTMF信号所代表的符号是否和输入的符号一致。 (DTMF (Dual Tone Multi-Frequency) is a single with two specific combination of audio signals to represent a kind of digital signal coding techniques. Two monosyllabic different frequency, on behalf of the numbers, or the realization of the functions are also different. Eight kinds of frequency of use on behalf of telephone on the 16 keys, 10 numeric keys 0 ~ 9 and 6 function keys*,#, A, B, C, D. The frequency of specific composition of reference books. Requirements: (1) According to the keyboard input of symbols, the use of MATLAB have a corresponding DTMF signal (2), respectively, using FFT algorithm and the Goertzel algorithm DTMF signal spectrum and frequency spectrum draw (3) According to DTMF signal frequency spectrum to determine represented by symbols and input symbols unanimously.)

Finds the convolution matrix of two input vectors

说明：  基于加权RLS的自适应去混响算法，包括了混响音频的样本和去混响后的样本，对其运行演示听取到语音处理前后会有些一点儿的差异(Adaptive-Dereverberation-Algorithm-master)

kohonen网络Matlab实现案例，内含具体语句说明，十分详细。 该案例 的准确率在70 左右(ANN(Kohoen))

orthogonal projection algorithm

说明：  利用那个matlab进行图像处理的几个常用的.m文件，需要自己考进自己的处理目录就可以正常使用了。(Using the matlab image processing of several commonly used. M files, you need to test their processing into its own directory to be normal use.)

相控阵天线测试数据的模拟产生与稀疏分解，可用于故障诊断(Phased array antenna simulation test data generation and sparse decomposition can be used for fault diagnosis)

说明：  此程序基于VV算法的载波相位估计。该算法既可以估计载波初始相位差。这种算法估计的精确度高。(This program is based on the carrier phase estimation of VV algorithm. The algorithm can estimate the initial carrier phase difference. The accuracy of this algorithm is high.)
