simulation model from matlab. sharing for acedamic purpose

说明：  一个OFDM通信系统的matlab源程序，相信很多学通信的同学都用得着。(an OFDM system Matlab source, I believe many of the communications school students are worthwhile.)

程序对4发4收系统进行V-BLAST检测算法的仿真。发送信号采用QPSK调制，信道为准静态瑞利平坦衰落信道，引入的噪声为均值为0的高斯白噪声，接收端分别采用ZF、MMSE、ZF-OSIC、MMSE-OSIC四种检测算法，根据其误比特率比较性能。(V-BLAST detection algorithm simulation program 4 of 4 admission system. Send signals using QPSK modulation, channel quasi-static Rayleigh flat fading channel, the introduction of noise with mean zero Gaussian white noise receiving end, respectively, ZF, MMSE, ZF-OSIC, MMSE-OSIC four detection algorithm based on its The bit error rate of the comparative performance.)

labview 中通过调用MATLAB节点来对示波器数据进行小波去噪并显示(By calling MATLAB in labview nodes to wavelet denoising and display the data of the oscilloscope)

convolution 2/3 rate encoder

非线性材料反饱和吸收理论拟合，可以给出材料的非线性吸收Z扫描曲线(theoretical fit to reverse saturable absorption)

Emd 数据分析包 可以绘制希尔布特边际谱 包络谱等(Emd data analysis package，It can draw envelope spectrum and Hilbert-Huang Spectrum ,etc)

Converts geodetic coordinates in WGS84_LLA to cartesian coordinates in WGS84_XYZ.

有借鉴意义哦，BP神经网络的整个训练过程,空间目标识别，采用PM算法。( There are reference Oh, The entire training process BP neural network, Space target recognition algorithm using PM.)
