利用阵列随机共振系统处理AM信号，比较处理前后的加噪信号波形，可以发现SSR系统具有抑制噪声的作用，(Stochastic resonance system using array processing AM signals, comparing before and after adding noise signal waveform, can be found SSR system has a noise suppression effect)

Route trajectory with variable speed

这是一个关于基于VCSOA的光开关的仿真程序。仿真程序基于传输矩阵法设计的，将整个器件在轴向按折射率的不同分成很多层。计算了在外部抽运（即泵浦，加在放大器上的工作电流）呈现周期性变化时，放大器将输出一系列的光脉冲，即光开关。 ( This is a simulation package for computing the characteristics of the VCSOA when acting as an optical switch, which is designed based on TMM( transfer matrix method). The whole device is splitted into many segments in the axis direction according to different index. When the external pump is a periodic signal, the output of the VCSOA would be a pulse train, which can be used as optical switch. )

说明：  微电网的提出旨在实现分布式电源的灵活、高效应用，解决数量庞大、形式多样的分布式电源并网问题 。 开发和延伸微电网能够充分促进分布式电源与可再生能源的大规模接入，实现对负荷多种能源形式的高可靠供给，是实现主动式配电网的一种有效方式，使传统电网向智能电网过渡。(The purpose of micro grid is to realize the flexible and efficient application of distributed power, and to solve the problem of large number and various forms of distributed power grid connection. The development and extension of micro grid can fully promote the large-scale access of distributed power and renewable energy, and realize the high reliable supply of various energy forms of load. It is an effective way to realize the active distribution network, and make the traditional power grid transition to the smart grid.)

区别于matlab自带的fft程序，为自主设计的myfft程序代码(Different from matlab' s fft own procedures for self-designed program code myfft)

说明：  在原始信号加入白噪声，通过卡尔曼滤波去除噪声，恢复原始信号。(In the original signal to join the white noise through the kalman filter remove the noise, restore the original signal. )
