Capabilities and Features

With Communications System Toolbox™ Support Package for RTL-SDR Radio, you can use MATLAB® and Simulink® to design and prototype systems that process real time wireless signals. For example, you can receive and process wireless signals such as FM radio, airplane surveillance signals (ADS-B), and signals from smart meters (water or energy metering devices). You can also deploy your system on a low cost, single-board computer, such as Raspberry Pi, that has an RTL-SDR attached to it.

Support highlights include:

  • RTL-SDR radio as an I/O peripheral to receive streaming RF signals
  • Ability to design standalone SDR applications with an RTL-SDR connected to Raspberry Pi hardware using Raspberry Pi Support Package for Simulink
  • Configurable center frequency in the range of 22 MHz to 2.2 GHz (based on the tuner)
  • Configurable sampling rate in the range of 225-300 kHz and 900 – 2,560 kHz

About RTL-SDR

RTL-SDR is a popular, low cost hardware that can receive wireless signals. The RTL-SDR dongle features the Realtek RTL2832U chip, which provides I-Q samples through the USB interface. You can receive and demodulate various wireless signals across a broad frequency range.
