3D plot for PDP

Hi all,

I have 29 PDP plots, each plot corresponds to different receiving angle but one tx angle. I want a 3D plot for this case, Is it possible ? please help me with generic code.

Thanks in advance

Do you mean like a 3D plot where your tx angle is plotted against two different receiving angles that you use to create for example your 1st and 2nd PDP plot? If everything has the same dimensions you could just

plot3(tx,t1,t2)

and see what happens. Or try to post some example data if it needs to be more specific.

I want to plot something like this. Instead of absolute time I want angle representation. ex: 0deg: 10deg:180deg.

Hi, did you ever got through in plotting the 3D power delay profile?

Hopefully the following is helpful:

%just making up some data... you already have your own..

receivingAngle = 0:360;

txAngle = 10:10:180;

[receivingAngle, txAngle] = ndgrid(receivingAngle, txAngle);

PdP = exp(-(recievingAngle-txAngle).^2/100);

%notice that I have 361 receiving angles and 18 tx angles

%ndgrid replicates them with each other so they both become 361 by 18

%these are the same size (361,18) as my PdP data

%I can now use plot3

figure

plot3(receivingAngle, txAngle, PdP)

%formatting to make the plot look nice

grid on %helps visualise 3D plots

view(20,40); %give you the same angle as your plot

xlabel('receiving angle (deg)')

ylabel('tx angle (deg)')

zlabel('PDP')
