数字信号处理的matlab实现 2012版 该书为第二版本，具有更多的范例。(Matlab digital signal processing to achieve the 2012 edition of the book is the second edition, with more examples.)

核极限学习机，引入核函数解决ELM求解问题，一旦参数选定，结果就稳定下来，不再混入随机。在原来版本上加入自己理解改写，使得代码更容易理解。(Kernel extreme learning machine, kernel function is applied to deal with ELM to solve the problem, once the parameters selected, the result is stabilized, not randomly in the original version on becoming a member of their understanding, makes the code easier to understand)

对数据进行emd分解，可以自适应得到对应的模态分量(Emd decomposition of the data can be adaptive to get the corresponding modal components)

这是一个去马赛克工具软件，对实现图像分析和数码相机开发有着重要的价值．(This is a mosaic tools to software, the realization of image analysis and the development of digital cameras has an important value.)

用MATLAB在产生的观测数据中捕获其中PRN 号码为“5”C/A 码。 （1） 观测数据应该有一定的多普勒频偏D f（-10kHz〈D f〈+10kHz）； （2） 加入高斯白噪声，使其信噪比为-20dB； （3） 捕获成功后，应给出捕获标志，并给出估计的频偏和码偏值。(Generated by MATLAB in which observed data capture PRN number is " 5" C/A code. (1) there should be some observations of Doppler shift D f (-10kHz < D f < +10 kHz) (2) by adding Gaussian white noise, so SNR is-20dB (3) capture success After the capture flag to be given, and given the estimated frequency offset and code bias values.)

基于matlab的扩频通信系统仿真研究。主编：范伟，战兴群(Matlab-based spread spectrum communication system simulation. Editor-in-Chief: Wei Fan, Xing-Qun Zhan)

说明：  四种常见的归一化方法，归一化效果不错。应用在matlab环境下。(Four common normalization method, normalized results are good. Used in the matlab environment.)
