hht
三种实现方式,采用MATLAB编程语言,一种是法国研究者设计的G Rilling 2007
另一种是MATLAB文件交换中心由Alan Tan开发的plot_hht程序包,第三种是台湾中央大学数据研究中心提供的EEMD包。
其中,我使用了plot_hht程序包,其使用了三个终止条件,驻留分量的单调性,极值点与零点的个数相差不超过1,还有黄锷1998经典文献提出的
SD>0.1,单调性的判断,并不是去判定驻留分量是否是单调函数,而是当曲线是双曲线时,循环结束,由于没有考虑端点效应,程序比较简洁,好读懂,大家
学习HHT可以从这个程序包入手,在此抛砖引玉,希冀有人能比较这三种不同的算法的性能和时间复杂度,以及对各种信号的适应性。(3 of hht method)

start
用七元线形天线阵(ULA)
已知:信号中心波长为2,天线阵元的间距为1米,快拍数为2000,空中有四个
源信号,假设它们的频率:0.015, 0.05, 0.02, 0.035
四个源信号的方向分别为:pi/4 pi/3 pi/6 3pi/4
求:
1)在不加入噪声的情况下,画出传统波束形成法、Bartlett波束
形成法、Capon波束形成法的空间谱图;
2)在加入高斯白噪声的情况下,假设信噪比为10dB,画出传统波束
形成法、Bartlett波束形成法、Capon波束形成法的空间谱图。(7-element linear antenna array (ULA)
Known: the signal center wavelength is 2, the antenna element spacing of 1 m, the number of snapshots for 2000, the air there are four
Source signal, assuming that their frequency: 0.015, 0.05, 0.02, 0.035
The direction of the four source signals: pi/4 pi/3 pi/6 3pi/4
Requirements:
1) not to join the noise, to draw the traditional beam-forming method, Bartlett, beam
Formation method, Capon beamforming method of the space spectrum
2) by adding Gaussian white noise, assuming that the SNR is 10dB, to draw the traditional beam
Formation method, Bartlett, beamforming, Capon beamforming method of the space spectrum.)
