FM-radio

Decode an FM-radio

At LCM, we have a most general software-radio, which is not only limited to digital communication, but which can serve for analog reception as well. FM modulation is a simple analog modulation that is widely used in radio-stations. Most of the time, this analog-signal is accompained by a digital signal that holds information about the radio-station itself.

The goal of this project is to extract the audio-signal and output it through a soundcard, and in a second time to decode the digital information provided in the signal.
