Estimation-

通信信号中编解码技术的研究，通过生成OFDM信号，经过快速傅里叶变换与反变换，最后用16QAM解调，计算信噪比。(Communication signal encoding and decoding techniques, but by generating OFDM signals, through the fast Fourier transform and inverse transform, and finally with 16QAM demodulation, signal to noise ratio calculation.)

This program is testing referencing and dereferencing

语音信号处理实基于MATLAB的语音信号时域特征分析 要求： 按所学相关语音处理得的知识，通过网上学习、资料查阅，自己设计程序，给出某一语音信号的短时过零率、短时能量、短时自相关特征的分析结果，并借助时域分析方法检测所分析语音信号的基音周期(yu yin xin hao chu li)

语音信号进行分析、处理和设计。用MATLAB做变声器的原理是通过改变输入声音频率，进而改变声音的音色、音调，使输出声音在感官上与原声音不同。变声器是借助对声音音色和音调的双重复合改变，实现输出声音的改变。通过自己发声，共振峰频率的改变是基于重采样实现的(Speech signal analysis, processing and design. MATLAB do voice-changer works by changing the input frequency of the sound, and then change the sound of the tone, pitch, so that the output audio with the original sound in different senses. Voice Changer is the use of sound timbre and tone of the dual composite changes, realize the output sound changes. Through their own sound, formant frequency change is implemented based on resampling)

Moment s Legendre algorithm

说明：  matlab拟合数据，分为回归分析、曲线拟合及计算机模拟(it contains Regression analysis, curve fitting and computer simulation)

This is a simple script two illustrate the concepts of Probability density function(pdf) cumulative density function (cdf). Two help pdfs are also included to understand the pdf and cdf concepts.

这是使用matlab语言编写的卡尔曼滤波程序,很不错的程序!(This is the use of matlab language Kalman filtering procedure, the procedure is pretty good!)

追赶法 西安交大 数值分析 梅立泉 编程(solve the equation matlab)

说明：  有三种算法，分别是cmeans、fcm和som等对如iris和usps等数据的聚类。(There are three algorithms, cmeans, FCM and SOM to cluster data such as iris and USPS.)
