Hello all. I want to design an FM radio (transmitter + receiver) using Matlab (not Simulink). Is it possible in Matlab? If yes, how? I am using stereo headphones as antenna on my laptop but I don't know how to get the signal from the headphone into Matlab code. Best regards.

Is it possible to use X310 device as well, from Ettus Research?
Thanks

So, you're not actually wanting to use Matlab to do design, you want to use Matlab to implement the receiver.
Clearly, you're going to have to invest in some hardware.
Maybe while googling for that, consider also googling gnuradio and similar.

hello
Ethem can you answer me please
Iam using the RF Budget Analyzer in a project to measure the real Radio waves energy around us.
my laptop is toshiba tecra ( it has a mobile telephone built in it ) . in fact i dont have antina, but i modulate an old TV one.
the data was same with the antina and without using it .
my question is can i use my laptop without any ariel or antina ??
thank you in advance

It is likely that unless you add hardware, that at most you would be able to measure signal strength in the 2.4 GHz and 5 GHz ranges, using the built-in WiFi chips.
Only some WiFi chip manufacturers include the ability to ask about signal strength. With a laptop in particular, it is common for the manufacturer to use integrated chips that only do as much as the manufacturer needs at the time.
I would not expect that you would be able to access the signal measurements from your laptop's built-in phone, but I could be wrong about that.
