学习matlab的经典书籍，我就是通过它快速走上matlab学习之路的，现在奉献给大家。(Learning matlab classic books, I just go through it quickly learning matlab path, and now dedicated to everyone.)

创建一个高斯分布并画出其PDF曲线，文件设置为均值为0.其分散为1，参数可以调节(Create a Gaussian distribution, and Draw the PDF curve, the file is set to mean 0. The spread is 1, the parameter can be adjusted)

this is a program for model predictive control with MAC algorithm

说明：  This .rar file include two .m files. It s simple simulation of cdma and DSSS. Hope it will help you understand the theory.

维纳滤波语音增强算法:语音增强算法的维纳滤波器，通过scalart 1996提出的实现。使用一个决策指导的方法跟踪的先验信噪比。请注意，该信号的第一0.25sec用于模型的噪声，即，它是假定的演讲之后，0.25sec开始(Wiener Filter for Noisy Speech Enhancement, implemented as proposed by Scalart 1996. Uses a decision directed method to track the a priori SNR. Note that the first 0.25sec of the signal is used to model the noise, that is, it is assumed that speech starts after that 0.25sec)

对H矩阵进行高斯消元，另外附加了高斯消元的论文(The H matrix using the Gauss elimination, an additional Gauss elimination of papers)

anroid手机中BMI值计算，对于初学者而言是个不错的案例(anroid phone BMI values, for the beginner is a good case in terms of)

说明：  基于MATLAB GUI 设计的数字信号处理系统，可以实现基本的信号生成，信号分析和信号滤波以及简单的语音信号处理等功能。其中信号生成模块可实现正弦波、方波、三角波、高斯白噪声、chrip信号的生成和叠加；信号分析模块支持基本的傅氏变换下的频域分析功能；信号滤波模块可以实现数字低通、高通、带通、带阻下的切比雪夫、巴特沃思、椭圆滤波器的设计和滤波处理；语音信号处理模块可以实现音频文件的读取、播放、叠加噪声、滤波等功能。(Based on MATLAB GUI design of digital signal processing system, you can achieve the basic signal generation, signal analysis and signal filtering, and simple voice signal processing and other functions. The signal generating module can realize the sine wave, triangle wave, Fang Bo, Gauss, chrip generation and superposition of white noise signal; signal analysis module supports the analysis function of frequency domain Fourier transform basic conditions; signal filtering module can realize digital low-pass, high pass, band pass, band stop, Butterworth, the Chebyshev elliptic filter design filtering and processing of speech signal processing; module can realize audio files to read, play, adding noise, filtering and other functions.)

有较好的参考价值，自己编的5种调制信号，仿真效率很高的。( There are good reference value, Own five modulation signal, High simulation efficiency.)
