MATLAB

很有用的时频分析工具，内附各个函数的说明，方便调用。(Very useful tool for time-frequency analysis, containing a description of each function, easy call.)

仿真信号的FFT频谱和功率谱，绘制了emd分解结果，以及瞬时包络和瞬时频率图，还有Hilbert-Huang谱和Hilbert边际谱。(The FFT spectrum and power spectrum of the simulated signal, the emd decomposition results, and the instantaneous envelope and instantaneous frequency maps, as well as the Hilbert-Huang spectrum and the Hilbert marginal spectrum.)

Matlab code for Variable Selection

OFDM程序示例：采用64子信道，应用16QAM传输，每个子载波均传输相同的比特数4，不使用信道编码；使用迫零均衡和MMSE均衡，比较两者性能。(OFDM procedures Example: a 64-channel, application 16QAM transmission, each transmission subcarriers are the same number of bits 4, do not use channel coding the use of force balance and MMSE zero balance, compare the performance.)

说明：  用matlab编写的fft快速傅立叶变换及逆变换函数,其中flip1是供ditfft函数调用的倒叙子函数。(using Matlab fft prepared by the fast Fourier transform and inverse transform function, which is flip1 ditfft function call for the Warrior unreachable.)

求取互相关值，可以实现两个序列互相关运算、时延估计等功能。(By calculating the cross-correlation value, the functions of cross-correlation operation and time delay estimation of two sequences can be realized.)

天线方向图的波达方向，用于描述回波的方向图1，可以用于初学者学习使用(the antenna dir)

数值计算的类函数，运算能力超过Matlab(Numerical Calculation)

这是神经网络的30个案例的matlab程序，每个案例均采用了不同的神经网络方法(30 cases of neural network matlab program, each case is different neural network methods are used)

此代码为本人在做灰色关联度分析时所用的matlab代码，所用实验数据也在，可以直接运行，希望能对其他学习灰色关联度分析的人员有用。(This code is I do gray correlation analysis used matlab code, the experimental data are used, can be run directly, hoping to be useful for other learning gray correlation analysis of staff.)
