鲁棒控制作业

射频电路中各组件模拟，包括放大器、环形器、转接头、测试单元、smith源等(tools in radio frequency circuit, including amplifiers circles conversion networks smith.)

A local extremum of audio watermarking algorithm, matlab software watermark embedding and extraction operation, also gives some common attack method of audio watermarking attacks.

Matlab implementation af Schroeder algorithm

这是Matlab初学者编写的小程序，内容简单明了，比较适合刚入门的人学习(This is a small program written in Matlab beginners, the content is simple, more suitable for people just getting started learning)

这个包，包含了好多比较经典的MATLAB程序 这是本人收藏多年的成果，现在上传给大家分享(This package contains a lot of comparison classic MATLAB program which is the outcome of my collection for many years, and now upload to the U.S. to share)

学习并找到降噪方法，对语音信号背景噪声做处理，使得声音更清晰。(The background noise is the most common factor degrading the quality and intelligibility of speech in recordings. Spectral subtraction can lower the noise level without affecting the speech signal quality. In this paper, we have studied and implemented to reduce the background noise of the voice signal, and to make improvements to reduce the background noise of the experiment. Not only with the spectral subtraction of the noisy signal of the transformation, we improve the traditional spectral subtraction based on the introduction of the parameters, by adjusting the parameters(α、β、γ) to achieve better enhancement.)

里面有对img格式文件的读取方式，还有对图像进行低通和高通滤波的方法。(There is on img file format, and read the image low-pass and high-pass filter method.)

说明：  this is simple signal processing matlab code

用matlab编写的边界跟踪算法，用到了freeman链码和爬虫法，可以有效的跟踪单个物体边界，适合于初学者。( Prepared using matlab boundary tracking algorithm uses a freeman chain code and reptiles method can effectively track a single object borders, suitable for beginners.)

基于Elman神经网络的预测程序，可用于电力系统短期负荷预测 (Elman neural network-based forecasting process, can be used for short-term load forecasting of power system)
