code:

user=[6];
for t = 1:length(user)
        Xmax=1; 
        Ymax=1; 
        radius=2; 
        xsd=ones(1,user(t))*Xmax;
        ysd=ones(1,user(t))*Ymax;
        rrx=radius*sqrt(rand(1,N_UE(t)));
        thetarx=2*pi*rand(1,N_UE(t));
        xrx=xsd+rrx.*cos(thetarx); 
        yrx=ysd+rrx.*sin(thetarx); 
        th = 0:pi/100:2*pi;
        xunit = radius * cos(th) + Xmax;
        yunit = radius * sin(th) + Ymax;
            figure
            plot(xunit, yunit);
            hold on
            plot(ysd,xsd,'r^')
            hold on
            plot(yrx,xrx,'ko')
            hold on

The code executes and gives me the figure.

With respect to the figure i need to measure the distance between all users with respect to the base station.

Could anyone please help me how to measure it.

if you have more than one base station use pdist2

What is N_UE(t)

在 MATLAB Online 中打开

user=6;
d1 = zeros(user,1) ;
d2 = zeros(user,1) ;
for t = 1:length(user)
    Xmax=1;
    Ymax=1;
    radius=2;
    xsd=ones(1,user(t))*Xmax;
    ysd=ones(1,user(t))*Ymax;
    rrx=radius*sqrt(rand(1,N_UE(t)));
    thetarx=2*pi*rand(1,N_UE(t));
    xrx=xsd+rrx.*cos(thetarx);
    yrx=ysd+rrx.*sin(thetarx);
    th = 0:pi/100:2*pi;
    xunit = radius * cos(th) + Xmax;
    yunit = radius * sin(th) + Ymax;
    figure
    plot(xunit, yunit);
    hold on
    plot(ysd,xsd,'r^')
    hold on
    plot(yrx,xrx,'ko')
    hold on
    d1(t) = sqrt((xunit-xsd)^2+(yunit-ysd)^2) ;
    d2(t) = sqrt((xunit-xrx)^2+(yunit-yrx)^2) ;
end

with respect to the code

user=6;

d1 = zeros(user,1) ;

for t = 1:length(user)

Xmax=1;

Ymax=1;

radius=2;

xsd=ones(1,user(t))*Xmax;

ysd=ones(1,user(t))*Ymax;

rrx=radius*sqrt(rand(1,N_UE(t)));

thetarx=2*pi*rand(1,N_UE(t));

xrx=xsd+rrx.*cos(thetarx);

yrx=ysd+rrx.*sin(thetarx);

th = 0:pi/100:2*pi;

xunit = radius * cos(th) + Xmax;

yunit = radius * sin(th) + Ymax;

figure

plot(xunit, yunit);

hold on

plot(ysd,xsd,'r^')

hold on

plot(yrx,xrx,'ko')

hold on

d1 = sqrt((xsd-xrx)^2+(ysd-yrx)^2) ;

end

totally there are 6 users shown in black color as it is stated as 'ko'.

I want to display the users in different colors with respect to distance.

example: user with the first minimum distance with respect to (xsd,ysd) should be in one color,user with the second and third minimum distance with respect to (xsd,ysd) should be in another color,user with the fourth and fifth minimum distance with respect to (xsd,ysd) should be in another color and last user in different color.

Could you please help me on this.
