FFT_3octave_A

一篇描述非线性滤波的经典文章，推荐给大家，文中有程序的介绍。(a description of the classical nonlinear filtering articles, recommended to you the text of the procedures introduced.)

Fourier transform and DFT (Fourier transform)

信号处理用的软件，振动分析用的。频域分析、时域分析(Signal processing software used, vibration analysis used. Frequency domain analysis, time domain analysis)

用于对简单电力系统网络的潮流计算，只需输入线路元件参数，节点电压初值，PQ,PV节点的初值，即可输出各节点电压，平衡节点的功率，线路的功率。(for easy power system)

This work outlines the application of ground-based GPS to climate research and meteorology without omitting the fact that precise GPS positioning can also highly benefit using numerical weather models for tropospheric delay determination for applications where GPS troposphere estimation is not possible, for example kinematic and rapid static surveys. In this sense, the technique of GPS-derived tropospheric delays is seen as mutually improving both disciplines, precise positioning as well as meteorology and climatology

相关噪声模型和相关函数计算 相关函数是平稳随机过程的重要数字特征，根据观测记录的信号波形或者一串数据序列，来估计该信号的自相关函数是信号处理的重要方法之一。(correlation noise model and correlation function)

This is Expectation Maximization algorithm code.

说明：  这个一个用matlab写的关于二值图像游程编码的实例(binary image coding)

确实是个好方法！确实是个好方法！确实是个好方法！确实是个好方法！(it is really a very very good method!it is really a very very good method!)

为了研究系统在受到外界干扰情况下的性能，特别从输入端加入了噪声干扰，仿真效果明显。(this progrmme is set to test the system performance .)
