一个好用的SvmPcaKnn的数据分类集合程序

The document describes seismic signal processing. Main function is to extract the edge of the seismic signal.

说明：  PLL性能,仿真,设计handbook,总结了常用的PLL结构和性能,对设计PLL很有帮助(PLL performance,simulation,design handbook)

Phase shift keying simulation

文基于小波分析的特点，提出了一种对信号进行多重小波 变换的自适应去噪法，该方法不仅克服了小波去噪软硬阈值法的局限性，而且解决了自适应滤波中参考信号选取难的 问题，将该方法用于脉搏信号降噪，得到了满意的去噪效果。(The text features based on wavelet analysis, proposed an adaptive multi-wavelet transform for signal denoising method, this method not only overcomes the limitations of hard and soft thresholding method of wavelet de-noising, and resolve the reference signal adaptive filtering Select the difficult problem of the method is used to the noise of the pulse signal, and been satisfied with the denoising effect.)

自己写的程序，处理人体三维数据手部数据时，对指定域进行简化(Write their own procedures when dealing with three-dimensional data of human hand data on the specified domain to simplify)

在扩频空域系统，一个spreadwatermark信号隐藏在另一个扩频信号相同的频谱。水印是将一个小秘密throughmodulation与基于密钥的PRNS准备，而直接作为第二扩频信号的原始媒体。一个水印信号的引入到原来的媒体传播的许多信号样本，以便在每个样品watermarkenergy可以减少到一个不起眼的水平对人类感知系统。此外，由于该PRNS嘈杂的性质

基于Matlab的指纹识别程序 对指纹图像进行gabbor滤波、二值化、腐蚀等适当处理后 通过SVM等算法 可以识别出新指纹图像是否在原有数据库中。可以用于演示小型的指纹识别系统 (Matlab-based fingerprint identification procedures carried out on the fingerprint image gabbor filtering, binarization, corrosion, etc. After appropriate treatment, such as through the SVM algorithm can identify a new fingerprint image is in the original database. Can be used for demonstration of small-scale fingerprint identification system)

使用MATLAB对特定信号进行频谱分析，画出幅度和相位谱的图像，并包含卷积运算和验证程序(The use of MATLAB to carry out a specific signal spectral analysis, to draw the magnitude and phase spectrum of images, and includes the convolution operation and the verification process)

the Gradient Projection Algorithm for Matlab coding

This is an classical infinite impulse response (IIR) filter, with certain parameters.
