GNU Radio

GNU Radio is an open-source software toolkit that allows users to build and simulate radio systems using software on a computer. It provides a flexible framework to process and analyze signals, making it easier to create applications for wireless communication, signal processing, and amateur radio. Users can design systems by connecting various software blocks that represent different functions, without needing extensive programming knowledge. GNU Radio is widely used by hobbyists, researchers, and professionals to experiment with radio technologies and develop innovative solutions in telecommunications and signal analysis.
