FM radio plays a large part in many peoples' lives. A digital stream of information known as the Radio Data System (RDS) can be transmitted alongside the audio signal in an FM radio broadcast. This digital signal may contain information such as the current song, traffic alerts, and emergency notices. Using MATLAB, a method is presented by which the RDS data may be digitally extracted from multiple FM broadcasts simultaneously. This method's parallel nature makes Digital Signal Processing (DSP) technology, such as a Field Programmable Gate Array (FPGA), an ideal platform for implementation.
