Source in FDTD
Hello People.
I have a simple question.
I´m using FDTD simulations to calculate the power of the signal on a scenario location.
I´m using a soft source that is a sinusoid modulated with a gaussian pulse with a determinate frequency.
I apply the source in the time domain and...
Hello guys!!
I´m working with FDTD+CPML with the objective of do the characterization of a radio channel.
I have done from the power delay profile, if the channel suffers from frequency selectiveness or flat fading.
Now I need to calculate the coherence distance to calculate the coherence...
how to run two matlab function same time
Hello Everyone.
I´m computing a FDTD simulator to study the radio channel characteristics using power delay profile. I use a scenario 2550px x 2550px and I need more than 2 hours to have some kind of results. I´m reading about parallel computing with...
Help FDTD+CPML urgent
Hello,
I'm working in FDTD+CPML and I need urgent help.
I´m simulating the situation of the paper that I send in attach.
In the case of PEC buildings, I can´t get the results of power delay profiles shown in the paper. I use a different mode than they, I use TEz mode...
power delay profile
Hello all.
I'm working on FDTD + CPML and for now my objective is to plot the power delay profile or for other words a graph with time in order of power.
I´m using TEz mode.
The manner that I´m calculating the power in dBW is...
Re: FDTD + CPML -> PDP
Hi, thanks for answer.
I use a pulse.
Jmax =1000;
alpha = (4/(32*dt))^2;
source=zeros(1,nSteps);
for n=1:88%(9 e 30)
source(n)= Jmax*(exp(-alpha*(((dt*n)-(32*dt))^2)));
end
then I apply
Hz(x,y)=source(x,y);
Thanks for attention
Added after 4 hours 14 minutes...
fdtd 2d cpml
Hi everybody.
I´m working with FDTD + CPML.
I´m simulating a typical scenario with 6 buildings (PEC structures) and in other situation (er = 3.0 e sigma = 0.005 S/m(electric conductivity).
For now I´m trying to plot the Power Delay Profile and I think, when comparing with the...
