C编写的QPSK调制解调，很有用，值得学习，代码编写很规范(Written in C QPSK modulation and demodulation, very useful, it is worth learning, very standardized coding)

光栅模式传输 运用耦合模理论，有公式推导，直接明了，可以更改参数(Optical fiber grating transmission function simulation and may, according to the need of reality, change all kinds of parameters )

希望对大家学习有所帮助，如果大家对此有什么看法，联系我 (Would like to help everyone to learn, what if everyone has this view, contact me)

说明：  使用3种方法（卡尔曼，巴特沃斯，小波）处理肌电信号，得出了关于那一种动作的各快肌肉参与情况。(The three methods (Kalman, Butterworth, Wavelet) were used to process the EMG signal, and the fast muscle involvement of that type of action was obtained.)

一种最简单的LMS算法，自适应滤波器中经常采用的算法(LMS MATLAB Adaptive filter)

说明：  提出了一种改进高阶Butterworth低通滤波器性能的设计方法。首先对高阶Butterworth低通滤波器的极点 进行重新分布，得出改进型Butterworth低通滤波器。性可以由其在基波电压初相位为零时的特性所唯一确定(Periodic voltage and current waveforms on the start time of its corresponding harmonic component of the relationship between the initial phase of research, pointed out that the characteristics of harmonic sources can be its initial phase in the fundamental zero-voltage characteristics of the CD a definite)
