I am a student and for my thesis i need to study a multipath channel in an urban enviroment, setting some transmitter and one target in motion.
I am using the comm.RayTracingChannel object to set up the receiver velocity, but i need to study a case where the transmitter move too.
There is a way to do this on Matlab? Thank you all very much

You’re correct that the comm.RayTracingChannel object in MATLAB only allows you to set the velocity of the receiver, not the transmitter. This is because the object is designed to model the channel response based on the receiver’s perspective.
If both the transmitter and receiver are moving at the same speed in the same direction, it’s equivalent to them both being stationary. If they’re moving at different speeds in the same direction, it’s equivalent to one of them being stationary and the other moving at the speed difference. The same concept applies if they’re moving in different directions.
So, even though comm.RayTracingChannel doesn’t allow you to directly set the transmitter velocity, you can still model a moving transmitter by adjusting the receiver velocity to be the relative velocity between the transmitter and receiver.

Thank you, i Will procede with this option.
