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 time in order to know if the channel suffers from slow or fast fading. For this I think that I need to do a time-space correlation function from the data of FDTD, but I´m lost and I´m not seeing how to do that.

If someone can help me I appreciate.

There is anything more (other parameters possible to calculate by postprocessing FDTD Ez) that I can do to characterize a radio channel by using FDTD??

Thanks very much

Cheers

.

I think more people could help you if you try to give formulas/definitions
of some of your terms.

For example, I don't know what coherence distance or coherence time
are but a formula or definition in terms of electromagnetic fields would
probably be enough for me to quickly decide if I can or cannot help.
