Hi Nicolas,
The array returned to you represents the impulse response of the channel, detailing the time delays and attenuation of multipath components, not directly the power trend due to Doppler fading.
For example,
rtchan = comm.RayTracingChannel(ChannelFiltering=false);
cir = rtchan();
gives you the channel impulse response in the variable "cir".
If you are interested to get the power-delay profile, youd can use this command:
showProfile(rtchan);
Please refer to the documentation for better understanding of the different use-cases with the "comm.RayTracingChannel" System Object:
I hope this helps!
