进行LTE 信道估计仿真器，对LTE进行信道估计，在LTE系统中是一个很重要的部分，是做链路级仿真必要步骤。(LTE channel estimater)

An extra file fdct_usfft_path.m is included in fdct_usfft_matlab directory. This script needs to be called to append several subdirectories into the searching path.

Peak finding and measurement

对于一段有杂音的音频信号，用过多种方式去除，建立多种经典滤波器，并比较优劣。(For a period of noise audio signal, used a variety of ways to remove the establishment of a variety of classic filter, and compare the pros and cons. )

l曲线的岭参数估计确定相关参数。。。。。。。。。。。。。。(The ridge parameter estimation of the L curve determines the relevant parameters.)

说明：  一个matlab神经网络工具箱，其中包含RNN,CNN等(Matlab neural network toolbox)

小波分析非常好的学习资料，都是源码，希望对大家有所帮助！(Wavelet analysis is very good learning materials, all source code, want to help you!)

Earthquake Engineering and Structural Dynamics(You can input any number of stores by giving the mass, stiffness and damping values. Input the gamma and beta values which are related to Newmark Integration Mtd. Press Newmarks Integration button to input the values. Input the any number of storey that you expected to see the deflection for particular Earthquake. Press “Storey No” button to get that number. If you like only, you will input the period and press “Period” button. Finally press calculate button to see final results. Also you can see the both graphs in log scales also.(Please right click on the graph as shown above). You may see what type of analysis method is used. (Average acceleration relation ship or Linear variation of acceleration).)

说明：  建立主成分分析和因子分析界面，对给定的随机数据进行主成分分析和因子分析(Establishment of principal component analysis and factor analysis interface for a given random data principal component analysis and factor analysis)

用遗传算法优化BP神经网络的matlab源代码，在matlab 7.0中实现(BP neural network optimization using genetic algorithm matlab source code, implemented in matlab 7.0)
