Hello everyone, I am analyzing a real urban environment taken from open street map (like google maps). In this I am looking at multipath propagation through the raytracing model, where I create the multipath channel between transmitters and receiver moving through the comm.RayTracingChannel object. Since I am not providing any signal as an input to the channel, what the channel returns to me is an array in which there are samples that describe the multipath to me. What I would like to know is whether what is returned to me is the impulsive response of the channel, or simply an array of samples describing to me the power trend due to the fading generated by the doppler effect. I think it is this second option, but I would like some confirmation.

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!
