PSO-BP(MATLAB)

关于扩展卡尔曼滤波的MATLAB程序 其目标是跟踪移动物体进行定位(Multi-sensor optimal information fusion Kalman filters with applications)

说明：  计算lyapunov指数谱，并能计算最大lyapunov指数(calculating lyapunov exponent spectrum and the max value of lyapunov exponent)

基于MATLAB串口数据采集系统及滤波源码，可以运行(Based on MATLAB serial data collection )

MATLAB进行模糊统计，得到模糊分布(隶属函数)近似解析表达式(MATLAB fuzzy statistics, get fuzzy distribution (membership function) approximate analytical expressions)

1.录制一段自己的语音信号,对录制的信号进行采样 画出采样后语音信号的时域波形和频谱图 给定滤波器的性能指标,采matlab设计数字滤波器,并画出滤波器的频率响应 然后用自己设计的滤波器对采集的信号进行滤波,画出滤波后信号的时域波形和频谱,并对滤波前后的信号进行对比,分析信号的变化 回放语音信号。2.(1. Recorded his voice for some signal, the signal is sampled on the record draw sampled speech signal time-domain waveform and frequency spectrum performance for a given filter, mining matlab digital filter design, and draw the filter frequency response then use their own filters designed to filter the collected signals, to draw the filtered time domain waveform and frequency spectrum, and comparing the signal before and after filtering, analysis of signal changes playback of audio signals. 2.)

非线性系统观测器的设计：LMI方法（论文及程序）(LMI nonlinear observer)

这是数字信号处理的程序，里面的子程序也重新整理好的，本人已经调试成功！(This is the digital signal processing program,it contains the subcode and I have debugging it sucessfully!)

从给定的一系列点找出最佳拟合椭圆,如果无法找出拟合椭圆，将返回一个空矩阵(fit_ellipse- finds the best fit to an ellipse for the given set of points.)

frequency synchronization for ofdm

自己写的，模式识别最近邻算法实现，配有IRIS数据集，非常实用(Their own writing, pattern recognition, nearest neighbor algorithm, with IRIS data set, very useful)
