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)

一维移动最小二乘法以及最小二乘法的曲面拟合，可以直接使用(One dimensional moving least square method, which can be used directly)

说明：  无线通信信道编码TURBO码的MATLAB+SIMULINK仿真程序！(Wireless communication channel coding TURBO code MATLAB+ SIMULINK simulation program!)

说明：  地震数据时频分析与分频处理，需要的带走吧，很不错的(Time-frequency analysis and seismic data processing division, need take it away, it is good)

周期图法各种改进,周期图法各种改进,周期图法各种改进(Periodogram various improvements)

LMS算法是一种自适应算法，也能够很好用在数字预失真中(LMS algorithm is an adaptive algorithm, and can well be used in digital pre-distortion in)

说明：  是matlab语言，对阶跃折射率分布锥形光纤模型中的光场分布进行了模拟。 (Is the matlab language, on the step refractive index distribution of tapered fiber-optic model of optical field distribution are simulated.)
