pcm的coding代码,可以用来在语音编码中使用。(pcm code of coding， can be used at the use of speech coding.)

是一種用以衡量兩張數位影像相似程度的指標。當兩張影像其中一張為無失真影像，另一張為失真後的影像，二者的結構相似性可以看成是失真影像的影像品質衡量指標。(Is a digital image to measure the similarity of two indicators. Two images when one of them is undistorted image and one for image distortion after the structural similarity between the two images can be viewed as a measure of the quality of the image distortion.)

在输入输出信号中加入高斯白噪声。这是在很多工程领域必须加入的。此文件是matlab中信号加入高斯白噪声的文件(In the input and output signals in white Gaussian noise. This is in many engineering fields must be added. This file is in matlab adding Gaussian white noise signal file)

说明：  基于MATLAB单神经元PID控制源程序(MATLAB-based single neuron PID control source)

复倒谱域滤波去除信号混响成分。利用复倒谱域变换与复倒谱滤波的方式去除单通道语音信号中的混响成分，提高语音质量。(Complex cepstrum domain filtering to remove the reverberation signal component. Using complex cepstrum and complex cepstrum domain transform filter Wave way to remove single-channel voice signal reverberation components, to improve voice quality)

Tsai标定法的matlab实现 完成图像坐标到世界坐标的转换(Tsai calibration method to achieve the completion of the matlab image coordinate to world coordinate conversion)

BIRCH (balanced iterative reducing and clustering using hierarchies) is an unsupervised data mining algorithm used to perform hierarchical clustering over particularly large data-sets. An advantage of Birch is its ability to incrementally and dynamically cluster incoming, multi-dimensional metric data points in an attempt to produce the best quality clustering for a given set of resources (memory and time constraints). In most cases, Birch only requires a single scan of the database. In addition, Birch is recognized[1] as the, "first clustering algorithm proposed in the database area to handle noise (data points that are not part of the underlying pattern) effectively".

IDW距离反比加权方法，一些自适应信号处理的算法，基于互功率谱的时延估计。( IDW inverse distance weighting method, Some adaptive signal processing algorithms, Based on the time delay estimation of power spectrum.)

关于ds_cdma系统的仿真，包括成型滤波，扩频编解码，调制解调等的子程序(About ds_cdma system simulation, including the shaping filter, spread spectrum encoding and decoding, modulation and demodulation, etc. subroutine)

matlab中fsolve语句数值效果较好，采用的解法是将方程组转化为最小二乘问题，调用指令lsqnonlin求解，所以，它参数的选取和优化指令的用法是一致的(matlab numerical results in fsolve statement better solution is to use the equations into a least squares problem, call the command lsqnonlin solution, therefore, it is parameter selection and optimization of instruction is consistent with the usage of)
