经典功率谱估计的MATLAB程序，需要的可以看看，验证过了(Classical power spectrum estimation of the MATLAB program, the need to look at, been verified)

OFDM信道估计，该文件夹包括19个M文件，包括误码率检测，插值计算，瑞利信道等(OFDM channel estimation, the folder includes 19 M files, including bit error rate detection, interpolation, Rayleigh channel, etc.)

1.录制一段自己的语音信号,对录制的信号进行采样 画出采样后语音信号的时域波形和频谱图 给定滤波器的性能指标,采matlab设计数字滤波器,并画出滤波器的频率响应 然后用自己设计的滤波器对采集的信号进行滤波,画出滤波后信号的时域波形和频谱,并对滤波前后的信号进行对比,分析信号的变化 回放语音信号。2.(1. Recorded his voice for some signal, the signal is sampled on the record draw sampled speech signal time-domain waveform and frequency spectrum performance for a given filter, mining matlab digital filter design, and draw the filter frequency response then use their own filters designed to filter the collected signals, to draw the filtered time domain waveform and frequency spectrum, and comparing the signal before and after filtering, analysis of signal changes playback of audio signals. 2.)

说明：  介绍MATLAB语言的一些基本语句，以及基本的编程方法。图形的绘制及GUI。(Introduce some basic MATLAB language statements, and basic programming. Graphics rendering and GUI.)

基于支持向量机的人脸年龄估计matlab仿真。(Face Age estimated based on support vector machine matlab simulation.)

感应双馈发电机系统的仿真，有借鉴意义哦，基于混沌的模拟退火算法。( Simulation of doubly fed induction generator system, There are reference Oh, Chaos-based simulated annealing algorithm.)

说明：  借助MATLAB实现高通数字滤波器的设计(Using MATLAB to achieve high-pass digital filter design)

双馈电机 控制 波形很好 参数调节的很正确 得出了好的控制效果(Double-fed motor control waveform parameter adjustment is very well drawn correctly good control effect)

Artificial neural network for prediction

代码主要计算Daubechies紧支集滤波器系数L0_d和H1_d,然后采用这两个系数对信号进行小波分解(The main calculation code compactly supported Daubechies filter coefficients L0_d and H1_d, then the use of these two coefficients of wavelet decomposition signals)
