Hello all. I want to design an FM Radio (Receiver + Transmitter) in Matlab. Is it possible to do so in Matlab? If yes, how? I will use stereo headphone as the antenna. Regards.

You probably will not be able to receive signals from your headphone jack. You can probably transmit from it but headphone jack A/D conversion is output only. You can probably do something with the microphone jack but then again i do not know the A/D sampling will be in the FM range. Doing a quick search online I see that the headphone and microphone jack is in the 22.05 or 24 kHz range and if memory serves me correctly FM radio is in the VHF part of the radio spectrum and thus in the 100 MHz range.
In your comment about how the mobile phone uses the headphone cord as an antenna you are correct however the mobile device has extra circuitry that your laptop doesn't. it has extra circuitry to separate the radio frequency and the audio frequency.
How much $$$ are you willing to spend on this endeavor?
