matlab 源码,基于小波变换的语音信息隐藏的实现,对原始语音信息和水印信息都经过三层小波分解处理后,将水印信息的低频信号嵌入原始语音信号的部分高频信号部分实现隐藏.源代码不仅给出隐藏过程,并且给出的在随机噪声,重采样,信息压缩情况下的抗攻击特性.源代码清晰有注释(matlab source code, based on wavelet transform voice messages hidden realize, the original voice information and watermark information after a three-treatment, after wavelet decomposition, the watermark information embedded in the low-frequency signals of the original speech signal realize some hidden part of high-frequency signals. source code is given not only to hide the process, and given in random noise, resampling, compression of information in case of anti-attack features. source code has a clear Notes)

说明：  Vblast，不同的编码方式qam，qpsk等，MMSE检测。不同天线数目设计。(very good for vblast MIMO beginners)

This document will describe some of the general usage of MATLAB s Data Acquisition Toolbox (DAT). The software in the toolbox allows MATLAB to acquire data from sensors and to send out electrical signals that can be used to control or drive external devices. We will be using this toolbox with two different pieces of hardware. One is the sound card built into your laptop, the microphone and speaker will serve as the data acquisition (and output) devices. The sound card provides convenience because it will allow you to test the DAT outside of the lab. We will also be using Measurement Computing data acquisition cards that will ¯ t into your laptops PCMCIA slot, these devices will be in the class laboratory. The data acquisition (DAQ) cards allow your computer to acquire data from many different types of sensors.

利用matlab实现归一化处理，可用处理大量数据(Using matlab to achieve normalization processing, handling large amounts of data available)

一个用在simlink 中用 dsp builder建立的FIR滤波器，每个波形都有波形显示，是学习DSP builder和FIR滤波器好资料。(One used in the FIR filter using dsp builder simlink established, each waveform has a waveform display, learning DSP builder and FIR filter good information.)

PCA for image compression, Sanger s algorithm implemented with neural networks

说明：  matlab例程源码，有很好的参考价值(matlab routines source, has a very good reference value)

说明：  在MATLAB环境下读取TXT文件的程序集合(In the MATLAB environment to read TXT files collection)

合成孔径雷达回波信号的建模，条理清晰，思路明确，赶紧下载吧。(Synthetic aperture radar echo signal is modeling, their clarity, ideas clearly, to download it. )

本段程序实在MATLAB环境下对输入的语音序列x进行MFCC参数的提取，返回MFCC参数和一阶差分MFCC参数。(Voice input sequence x extracted MFCC parameters, return parameters and the first-order difference MFCC MFCC parameters)
