谱哈希，matlab

MATLAB环境下对于含平稳噪声的带噪语音利用谱相减算法进行处理，原始语音请命名为“origin.wmv"，处理后的语音为”enhanced.wmv"。rar内含有我自己做好的语音处理结果，可以用你自己的待处理语音替换它们，请放在同一目录下！(MATLAB environment containing stationary noise for Noisy Speech using spectral subtraction algorithm for processing, the original voice please named origin.wmv , after the voice for enhanced.wmv . rar contains my own voice to do a good job dealing with the results, you can use your own voice to be processed to replace them on the same directory, please!)

说明：  EMD经验模态分解算法程序，适合非线性，非平稳时间序列的处理(EMD empirical mode decomposition algorithm program)

长周期光纤光栅有着很广泛的应用前景,关于长周期光纤光栅的理论分析也很成熟,而具体如何实现其传输谱特性的 仿真却报道很少(Long-period fiber grating has a very broad application prospects, on the theory of long-period fiber grating analysis is also very mature, and specifically how to achieve its transmission spectral characteristics of the simulation are few reports)

使用近似分数阶微分算子的方法，将分数阶系统近似成整数阶系统，封装成分数阶系统模块，再进行系统最优控制器的设计。

验进行了OFDM基带系统的设计与仿真，映射方式采用QPSK调制，并采用了128点IFFT/FFT，利用其中的64路来传送有用数据，并仿真得到了信噪比在2-14dB时的误比特曲线，并与理论值进行了比对。从仿真结果来看，在信噪比为12dB时即满足信噪比小于10-4。

在字符识别中，往往需要将字符细化，以便为今后的字符识别提供有利条件，本文采用matlab编程，很好的实现了字符细化，为字符识别做好了充分的准备。
