This file is used for generate OVSF code in Matlab. Check this and enjoy using it

本例子包括分析数据的txt文件，主要用matlab程序，基于小波分析算法进行发动机波形分析，进而进行发动机故障诊断(ignition pulse width waveform analysis based on wavelet)

about matlab in persian language

this is for Korean and kind of signal processing.

说明：  Matlab code of a Genetic algorithm

是一种双隐层反向传播神经网络，未来线路预测,分析误差,通过虚拟阵元进行DOA估计。( Is a two hidden layer back propagation neural network, Future line prediction, error analysis, Conducted through virtual array DOA estimation.)

说明：  用R语言写出的copula-GARCH函数(copula-GARCH function using R language)

FFA（快速折叠算法），实现噪声中的周期信号检测，及周期估算(FFA (fast folding algorithm), the realization of the periodic signal in noise detection, and cycle estimates)

说明：  用matlab进行陷波器的设计，单频率周期正弦信号加上宽带白噪声，用自适应算法进行分离。(It is about filter design.Designed bymatlab,and the result is well.)

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)
