power_spectrum

一个简单的图象去噪的算法，利用原偶算法及曲率计算(a simple image denoising algorithm, dual use of the original algorithm and curvature calculation)

该程序是自己编写的，是基于matlab的多径信道的建立。该多径信道是基于电力线信道特性而构建的，其中的衰落系数是通过阅读大量文献而得到的。该程序能够顺利运行，并画出了信道的各个参数图。(The program is written by myself,which is to build a multi-path channel matlab based. The multi-path channel is based on the characteristics of the power line channel constructed, which is fading coefficients obtained by reading a lot of literature. The program can run smoothly, and draw a diagram of each parameter channel.)

说明：  MATLAB实现的图像缩小程序，已通过调试(err)

说明：  多目标优化nsga2算法，包括非支配排序以及函数测试(Multi objective optimization NSGA2 algorithm, including non dominated sorting and function testing)

系统可以利用声音信号产生带有回声的声音文件，并可以从带有回声的文件中消除回声而得到原声音信号；另外，系统还能从中估计反射物的距离(System can make use of the voice signals of the sound files with echoes and echoes from the document with echo and obtain the elimination of the original voice signal In addition, the system can also have to guess the distance from the reflective material)

说明：  正态总体参数的检验,调用ztest和ttest函数(Inspection normal population parameters)

读取csv文件 可以实现与matlab交互用，或与其他文件交互，程序较小但可用(read vsc files Interacting with Matlab can be achieved using the Read CSV file, or interact with other documents, the program small but can be used)

基于maglab/simulink平台设计的利用duffing振子检测微弱正弦信号，非常好的一个源程序，自己亲自调试，运行在matlab2012b上没有问题，仿真步长0.01s,采用RK四阶算法。若有问题，欢迎指教(Based maglab/simulink platform using duffing detect weak sinusoidal oscillator signal, a very good source, personally commissioning, operation without problems on matlab2012b, simulation step 0.01s, using the fourth-order RK algorithm. If questions, please advise)
