过采样精确重构余弦调制滤波器组的设计.rar(Reconstruction of oversampled cosine-modulated filter banks. Rar)

This code is about migration of seismic data.

OFDM比较经典的源码程序，包含了整个系统的仿真，及性能的分析(OFDM more classic source programs, including the simulation of the entire system, and performance analysis)

采用bootstrap方法重抽样，可以将小样本变成大样本，适合乏信息问题(Resampling bootstrap method, small samples can be turned into a large sample suitable for lack of information problem)

Usage of Matlab for beginners

将segy数据转成txt文件可用于地震资料(Txt will be converted into segy)

说明：  DDC下变频链路搭建，利用FDATOOL工具搭建CIC梳状滤波器、HB半带滤波器以及FIR滤波器；并用VHDL语言实现(DDC down conversion link is built, CIC comb filter, Hb half band filter and FIR filter are built by FDATool tool, and implemented by VHDL language)

Electromagnetic AC MOTOR actuator simulation

基于MATLAB实现的说话人识别程序，分别用bp、pnn、som、rbf、lvq等算法，对语音文件进行训练和测试，效果不错。~..~ 下面说明一下bprengong程序： 数据分别用来训练和测试两部分。 具体程序分为两部分，第一部分为：计算识别模型 变量v是mfcc处理以后的矢量。因为数据可能长短不一，所以放在同一进行截取。p的每一行代表一个语音数据（共15个）。变量Pr为每一行的最大最小值。变量T为目标值。输出神经元个数为15。 在训练阶段，如果用于训练的输入训练样本的类别标号为i（即语音数据的标号），则训练时设第i个节点的期望输出设为1。其余节点期望输出均为0。 在识别时，当一个未知类别的样本作用到输入端时，考查各输出节点的输出，并将这个样本的类别判定为输出值最大的那个节点对应的类别。 (err)
