三相静止坐标系与两相静止坐标系之间的变换关系(Clarke变换) (Three-phase static coordinate system and two phase transformation relationship between static coordinate system (Clarke transformation）)

USED FOR EXTRAPOLATION OF A SIGNAL

齿轮传动参数测定和公法线公差计算 可以用来优化齿轮的传动系统(Gear parameters measured and calculated tangent tolerance can be used to optimize the transmission gear)

人脸识别算法实现 (Face Recognition Algorithm )

自己编写的程序，产生Sierpinski衬垫图案,简易实现。附带在网上下载的两个Sierpinski程序供大家一起学习。(their preparation procedures have Sierpinski liner pictorial, simple to achieve. Fringe in the downloaded two Sierpinski procedures for all learning together.)

In this project, we have designed and implemented a method to estimate the dual frequencies in sinusoids immersed in additive white Gaussian noise. The Cramér-Rao lower bound (CRLB) for the signal model and a nonlinear least square frequency estimator are derived. The estimator is evaluated by numerical examples.

cyclic convolution and discrete spread spectrum

说明：  文章对OFDM技术作了介绍，主要涉及OFDM技术的基本原理，信道估计，同步技术等。(Articles on OFDM technology are introduced, mainly related to the basic principle of OFDM, channel estimation, synchronization technology.)

本程序主要是利用利用语音信号的基本特性进行谱熵端点检测(taep end detection)
