知名的 baseflight 四轴飞行器移植到匿名四轴的硬件上(Renowned baseflight quadrocopter transplanted into anonymous axis hardware)

录制一段个人自己的语音信号，并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，采用窗函数法和双线性变换设计滤波器，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；最后，设计一个信号处理系统界面。(Record a person s own voice signal, and recording the signal sampling draw sample after the speech signal time-domain waveform and frequency spectrum given filter performance indicators, using a window function method and the bilinear transform filter design and draw the frequency response filter then use the filter of their own design for the signal acquisition filtering, after filtering the signal to draw the time-domain waveform and spectrum, and filtering of signals before and after contrast, analysis of signal changes playback of voice signal Finally, the design of a signal processing system interface.)

介绍Matlab在化工方面的数值计算应用，课件主要讲述化工领域非线性、线性方程组的解法，插值、拟合和常见常微分方程的解法。(Introduced in the chemical aspects of Matlab numerical computing applications, courseware mainly about the chemical field of nonlinear, solution of linear equations, interpolation, fitting, and common ordinary differential equation solution.)

16QAM的误码率性能分析的matlab仿真 (These code are some matlab codes for BPSK modulator and demodulator in fading channels for wireless communications )

支持向量机用于回归，在MATLAB里实现的。方便好用(Support vector machines for regression, implemented in MATLAB in. Is easy to use)

语音基本间隙检测算法，voice activity detection(basic voice Gap Detection Algorithm, voice activity detection)

近红外光谱建模 进行定量分析 偏最小二乘法(very good)

对AR（4）模型的经典功率谱估计，并与真实功率谱作比较。采用了welch方法，协方差法，burg方法(For AR (4) model of the classic power spectrum estimation, and with true power spectrum for comparison. Welch method using covariance method, burg method)

关于实现低通滤波器的小程序,是matlab编程的,只不过装在word文档里,只要贴到matlab的m文件里,即能实现功能.对初学者有很好的借鉴意义.(on the realization of the low-pass filter small procedures, Matlab programming. just loaded word in the document, as long as Matlab affixed to the document m, It is able to achieve functional. for beginners have a good reference.)

说明：  简单的实现了weiner滤波的功能，可以用于信号处理，可以用(Simple implementation of the weiner filtering function can be used for signal processing)
