I couldn't able to find any information about it. What I meant is that creates a signal that behaves like it comes from air. So its amplitude always changing.At least time defined for the changing. How to achieve this? Is it possible??

If what you need is a sort of white noise, then you can use random number generators, e.g.:
rand() - uniform distributed,
randn() - normally distributed random numbers, or
randi() - uniform distributed integer numbers.

Actually what I tryna get is like in https://www.mathworks.com/videos/waveform-generation-using-mathworks-sdr-1554978351616.html In the video, where spectrum analyzer shows the real time signal with the help of SDR, I wanna get a signal like that without SDR and I wonder is it possible or not.

It's okay to use those commands to generate a random signal. But it won't give me a chance of modelling a real time signal. What I mean with 'real time signal' is that I expect it changes all the time (at least during the time I'll define)
