FFT

阵列信号处理工具箱，可以方便、快捷、准确调用库函数达到相应计算要求。(Array signal processing toolbox, can be convenient, fast and accurate calculation of call library functions to meet the corresponding requirements.)

这是我上传的第5个文件,是用于建模方面的,很有用,所上传的5个程序文件要协同工作才行(This is my uploads section 5, for modeling, very useful, by the five upload files to work together Caixing)

包括语音的录制程序，加噪程序，以及标准的噪声库，还有用谱减法实现带噪语言信号的增强等程序(ncluding voice recording program, noise procedures, and standards of noise library, as well as achieve the noisy speech signal enhancement using spectral subtraction procedure)

对数字散斑的形成仿真处理有全面的介绍 对研究数字散斑在各种方面的测量很有帮助 很有启发性(Simulation of digital speckle formation process with a comprehensive introduction)

用最大释然估计进行频率估计，并计算可拉美罗下界，通过蒙特卡罗实验进行计算。( Relieved estimates with the greatest frequency estimation and Latin Rao lower bound can be calculated by Monte Carlo experiments calculated.)

emd 代码程序 音频信号的采集和分解，用来做经验模态分解实验。(emd-code program audio signal acquisition and decomposition, used as empirical mode decomposition experiment.)

实现对matlab版本的libsvm的分类超平面的刻画，清晰的展示出分类结果。(a plot function for draw the hyperplane of the libsvm.)

图像经过二维傅立叶频谱分析后，用此函数可以求取频谱的环向、楔向特征。在图像分析中具有较大用途。(After two-dimensional Fourier spectrum image analysis, this function can be used to strike a spectrum of the ring, to the characteristics of wedge. In the image analysis with a larger purpose.)

一本介绍小波分析方法极其应用的书，从图书馆下载后还没看，感觉应该还不错(An introductory wavelet analysis method is extremely Application book from the library download not see, feel, should be pretty good)
