09-MIMO系统容量仿真程序
说明: function C=capacity(SNR,Nt,Nr)
%SNR=0; %定义信噪比为0HZ
A=10^(SNR/10); %信噪比的单位转换关系式
Im=eye(min(Nr,Nt)); %这里的"1"为发射天线和接收天线两者数目少的根数
sum=0; %初始化sum为0
for i=1:10000 %程序循环10000次
H=randn(Nr,Nt); %产生高斯信号源
if Nr<Nt
Q=H*H'; %求威沙特矩阵
else
Q=H'*H;
end
sum=sum+log2(det(Im+A*Q/Nt)); %10000次循环得到的信道容量总和
end
C=sum/10000 %10000次循环的平均值(function C=capacity(SNR,Nt,Nr)
%SNR = 0;% defines SNR as 0Hz
A = 10 ^ (SNR / 10);% s / N unit conversion relation
Im = eye (min (NR, NT));% here "1" is the number of the less number of transmitting antenna and receiving antenna
Sum = 0;% initialize sum to 0
For I = 1:10000% program cycles 10000 times
H = randn (NR, NT);% produces Gaussian signal source
if Nr<Nt
Q = h * H ';% to find the weissard matrix
else
Q=H'*H;
End
Sum = sum + log2 (DET (IM + A * q / NT));% sum of channel capacity from 10000 cycles
End
C = sum / 10000% average of 10000 cycles)

ADF:梯度矢量流GVF的一个改进
应用背景
梯度矢量流主动轮廓模型在图像分割领域风靡一时,在整个21世纪的头15年风头一时无两,至今在在TIP等顶级国际期刊仍然有论文发表。本文提出他的一个改进,主要动机是解决无限长深度凹陷问题等。
关键技术
ADF作为GVF的一个改进,主要是引入了几个机制,包括退化最小曲面扩散机制,无穷范数的使用等,使得扩散成为真正的各向异性,同时还引入了最优停止机制,获得模型的自动停止办法,效果非常好!
