      GNU Radio is a free & open-source software development toolkit that
      provides signal processing blocks to implement software radios. It can be
      used with readily-available low-cost external RF hardware to create
      software-defined radios, or without hardware in a simulation-like
      environment. It is widely used in hobbyist, academic and commercial
      environments to support both wireless communications research and
      real-world radio systems.
