分数阶差值，分数倍上采样，DUC模块中应用，在TVB2系统中仿真使用。(Fractional difference scores sampling times, DUC module applications, simulation using TVB2 system.)

this is about edge detection

基于matlab算法开发点云数据x/y/z坐标提取，算出相关粗糙度。(The point cloud data x/y/z coordinate extraction was developed based on matlab algorithm to calculate the correlation roughness.)

poisson问题有限元求解通用程序(线性元). 压缩包内exp.m包含了一个实际问题,matlab下直接运行即可,如效率不高,可适当修改网格参数h.(poisson problem of the finite element procedure for solving general (linear million). exp.m compressed package contains a real problem, matlab can be directly run, such as the efficiency is not high, may be appropriate to amend the grid parameter h.)

肖扬书中mimo LDPC 的仿真程序，通过。(Xiao Yang in the book mimo LDPC simulation program, was adopted.)

synchrouniouse machine simulation

mimo工具箱,仿真时的用处很大啊 节省不少时间(mimo Toolbox, simulation of very useful ah save a lot of time)

这是一个风力发电系统仿真模型，个人认为比较不错，供大家借鉴(wind power system)

DTMF(双音多频)是用两个特定的单音频组合信号来代表数字信号的一种编码技术。两个单音的频率不同，代表的数字或实现的功能也不同。可采用8种频率代表电话机上的16个按键，10个数字键0~9和6个功能键*、#、A、B、C、D。具体的频率组合见参考书。要求： (1) 根据键盘输入的符号，利用MATLAB产生对应的DTMF信号；(2) 分别利用FFT算法和Goertzel算法计算该DTMF信号的频谱并画出频谱图；(3) 根据频谱图确定DTMF信号所代表的符号是否和输入的符号一致。 (DTMF (Dual Tone Multi-Frequency) is a single with two specific combination of audio signals to represent a kind of digital signal coding techniques. Two monosyllabic different frequency, on behalf of the numbers, or the realization of the functions are also different. Eight kinds of frequency of use on behalf of telephone on the 16 keys, 10 numeric keys 0 ~ 9 and 6 function keys*,#, A, B, C, D. The frequency of specific composition of reference books. Requirements: (1) According to the keyboard input of symbols, the use of MATLAB have a corresponding DTMF signal (2), respectively, using FFT algorithm and the Goertzel algorithm DTMF signal spectrum and frequency spectrum draw (3) According to DTMF signal frequency spectrum to determine represented by symbols and input symbols unanimously.)
