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.)

matlab用于求解规划问题的工具包
推荐把这个工具整合到matlab中去,这个工具是私人的,不过大家都可以免费下载使用。下载后,只要在matlab中添加路径就可以使用这工具箱。
正在吸引我的是,这个工具箱建立了一种新的数据类型,使所有规划问题都整合在一起。
举例如下:
已知非线性整数规划为:
Max z=x1^2+x2^2+3*x3^2+4*x4^2+2*x5^2-8*x1-2*x2-3*x3-x4-2*x5
s.t.
0<=xi<=99(i=1,2,...,5)
x1+x2+x3+x4+x5<=400
x1+2*x2+2*x3+x4+6*x5<=800
2*x1+x2+6*x3<=800
x3+x4+5*x5<=200
在matlab中输入 x=intvar(1,5);
f=[1 1 3 4 2]*(x .^2)-[8 2 3 1 2]*x F=set(0<=x<=99)
F=F+set([1 1 1 1 1]*x <=400)+set([1 2 2 1 6]*x <=800)+set(2*x(1)+x(2)+6*x(3)<=800)
F=F+set(x(3)+x(4)+5*x(5)<=200) solvesdp(F,-f)
double(f) 80199
double(x) 53 99 99 99 0
intvar(m,n):生成整数型变量;
sdpvar(m,n):生产变量;
solvesdp(F,f):求解最优解(最小值),其中F为约束条件(用set连接),f为目标函数
double:显示求解的答案
intvar,sdpvar,生成的变量可以像矩阵一样使用,如例题显示。
