RTL-SDR Support from Communications System Toolbox

Design and prototype software-defined radio (SDR) systems using RTL-SDR with MATLAB and Simulink.

The RTL-SDR radio support package enables you to design wireless receivers using real-world signals. Using Communications System Toolbox™ in conjunction with an RTL-SDR USB radio, you can design and prototype systems that process real-time wireless signals in MATLAB® and Simulink®.

Wireless engineers, students, and hobbyists can learn to receive and decode real-world radio signals using this low cost RTL-SDR hardware connected to your computer.

Key Features:

  • RTL-SDR radio as an I/O peripheral to receive streaming RF signals
  • Configurable center frequency and sample rate
  • NooElec™ NESDR Mini USB Stick (R820T) and NooElec NESDR Nano USB Stick (R820T) SDR devices with frequency range 30MHz – 1.8GHz
  • Compatible with other RTL-SDR USB radios (e.g., Terratec T-Stick E4000)
  • Several application examples for getting started with RTL-SDR:
    • FM mono/stereo
    • FRS receiver
    • Spectral analysis
    • Frequency offset calibration
