互相关求时延差

The code is used for Homomorphic filtering

说明：  二维分数阶傅里叶变换，可以把数据经此变换后，变成2D分数阶域(Two-dimensional fractional Fourier transform, the data can be transformed by this into 2D fractional domain)

用差分方法计算带时变系数的波动方程,界面可视。(simulate the wave functions with time-varying coefficients)

说明：  线性系统理论，用龙格库塔法求解，极点配置(Theory of linear system)

Bluetooth is a wireless technology that allows computers, phones, headsets, PDA s and other devices to wirelessly communicate over short distances (up to 33 feet). Bluetooth uses radio waves (in the 2.4 GHz range), and is designed to be a secure, low power and inexpensive way of connecting and exchanging information between devices without the need for wires or cables to link devices together.

这个程序对简单LPC-10声码器做了一些改进，使其对浊音的激励变得较强，使用声激励LPC声码器来提高声音的质量。它与简单LPC-10音码器的差异是用激励检测器替换了基音检测器。(This program simply LPC-10 vocoder made some improvements to make them become a strong incentive voiced the use of acoustic excitation LPC vocoder to improve the sound quality. It sounds simple LPC-10 codec difference is replaced with the excitation detector pitch detector.)

利用小波变换算法对灰度图像进行压缩,效果比较好( Carries on the compression using the wavelet transformation algorithm to the gradation image，and the effect is good. )

说明：  此程序是一个将灰度图象转化为二值图象的程序,手动选择阈值(This program is a the gray image into binary image of the program, manually select the threshold value)

说明：  MATLAB课件，可以帮助快速学习MATLAB，介绍详细，有举例详解(MATLAB software can help fast learning MATLAB, introduced in detail, and explain, for example)

希尔伯特-黄变换的matlab程序，简洁明了、特别适合初学者。(hirblert huang transfer)
