小波去噪。。。程序完全可以运行，还有图形(Wavelet denoising. . . Program can run, there are graphic)

A SIMPLE BUT USFUL 2D FDTD MATLAB CODE(USFUL 2D FDTD MATLAB CODE)

DV-hop基于matlab的实习。实现matlab环境下的仿真(dv-hop which base matlab，youcan use it to findwsn)

平面波展开法计算的二维声子晶体带隙，分别是正方与圆形散射体形成正方格子声子晶体，最后输出了能带图的数据，需要自己用画图软件画出来。(Plane wave expansion method to calculate the band gap of two- dimensional phononic crystals, which are square with rounded square lattice formed scattering crystal, the final output of the energy band diagram of the data, so you need to use drawing software drawn.)

循环平稳算法估计载波频率程序，对BPSK效果好，(Estimation of carrier frequency program by cyclostationary algorithm)

说明：  归一化后截止频率为0.2的数字低通滤波器，并且能有效滤掉工频干扰，使心电信号有效表达信息。(The normalized digital low-pass filter with a cutoff frequency of 0.2, and can effectively filter out power frequency interference, so that the ECG signal can effectively express information.)

本文对@:AB及其衍变模型进行了分析和总结，提出了直交门槛一般化自回归条件异方差#< 90 8 17C -D@:AB*模型。通过模型平稳性测试、@:效果检定、@:AB效果检定、模型阶数鉴定、模型参数估计与模型诊断对模型进行 评估，作者认为这种模型在估计投资组合资产收益的波动性上优越@:AB及其衍变模型。 (In this paper, @: AB model and its evolution are analyzed and summed up the proposed DC-AC threshold generalized autoregressive conditional heteroskedasticity# < 90 8 17C-D @: AB* model. Smooth adoption of the model testing, @: the effect of test, @: AB test the effect of model order identification, model parameter estimation and model diagnostics to assess the model, the authors suggest that this model portfolios in estimating the volatility of capital gains on the superior @ : AB and its evolution model.)
