FM RDS Receiver with the RTL-SDR

An FM broadcast receiver with RDS (Radio Data System) demodulator and decoder using the RTL-SDR

This Simulink model implements an FM broadcast receiver with RDS (Radio Data System) demodulator and decoder. It is used for teaching analog and digital modulation in a real-world application using a low-cost hardware, the RTL-SDR.

The model provides an audio ouput of the radio station and displays text messages transmitted via RDS. A spectrum plot and signal constellation plots give insight in the operation of the FM demodulator, the BPSK demodulator and the timing recovery.

A detailed description is included in the package.
