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 original document that something's wrong.
The Power Delay Profile from the original document for the PEC situation, the power is almost always at the same level (for example the multipath components are almost always in 12dB) , and in my simulation, the power is always decreasing with time.
What is the normal behaviour of a power delay profile? with the specific case of PEC buildings and with the other case explained?
What do you think that could be the problem?
The file attached is the plot of the original document and mine.
Please I need some help.
Cheers
