Gnuradio

Open Source Software Radio (Gnuradio), or Open Source Software Defined Radio, is a free software toolkit for learning, building, and deploying software-defined radio systems. Launched in 2001, Gnuradio is now an official GNU project.

Introduction to the program

        Gnuradio is a radio signal processing scheme distributed under the terms of the GNU GPL. Its purpose is to give ordinary software developers the opportunity to explore electromagnetic waves and inspire their clever use of radio frequency waves.
        As is the definition of all software-defined radio systems, reconfigurability is its most important function. There is no need to buy a lot of transmitter and receiver equipment, just a device that can be loaded with signal processing software (here: Gnuradio). At present, although it only defines a few limited radio functions, as long as you understand the mechanism (algorithm) of the wireless transmitter system, you can configure it arbitrarily to accept it.
        Gnuradio originated as a fork of the Pspectra code developed by the SpectrumWare project team at MIT in the United States. It was completely rewritten in 2004. So today's Gnuradio no longer contains any code from the original Pspectra. It is also worth mentioning that Pspectra has been used to create the commercialized Vanu Software Radio.

        GNU Radio is a free software power builder kit. It provides signal operation and processing modules that enable software-defined radios to be implemented on low-cost radio frequency (RF) hardware and general-purpose microprocessors that are easy to fabricate. This kit is widely used by hobbyists, academic institutions, and commercial organizations to research and build wireless communication systems.

        GNU Radio applications are primarily written in the Python programming language. But its core signal processing module is C++ built on a microprocessor with floating-point arithmetic. As a result, developers can easily and quickly build a real-time, high-capacity wireless communication system.

        Although its main function is not an emulator, GNU Radio supports the study of algorithms for signal processing of pre-stored and generated data without RF hardware components.

III. Significance

        The real value of Software Radio GNURadio is that it allows engineers and designers to create on a low budget and with minimal effort. A large number of developers and users contribute a large code base and provide many practical applications for software and hardware. The combination of flexible hardware, open-source software, and a community of experienced users makes it the ideal peripheral for your Software Radio development.
