GNU Radio is an open-source toolkit for signal processing and software-defined radio (SDR). You build a processing chain from blocks in a graphical editor — filters, modulators, FFTs — and run it on simulated signals or a real radio receiver. RF and communications engineers use it for prototyping, testing and teaching. It runs mainly on Linux, and also on Windows and macOS.
