The Haswell/AVX2 column will work marginally faster on the right machine, but will crash on other CPUs.

GNU Radio is a free software development toolkit that provides signal processing blocks to implement software-defined radios and signal-processing systems. It can be used with 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.

Overview[edit]

The GNU Radio software provides the framework and tools to build and run software radio or just general signal-processing applications. The GNU Radio applications themselves are generally known as 'flowgraphs', which are a series of signal processing blocks connected together, thus describing a data flow.

As with all software-defined radio systems, reconfigurability is a key feature. Instead of using different radios designed for specific but disparate purposes, a single, general-purpose, radio can be used as the radio front-end, and the signal-processing software (here, GNU Radio), handles the processing specific to the radio application.

These flowgraphs can be written in either C++ or the Python programming language. The GNU Radio infrastructure is written entirely in C++, and many of the user tools are written in Python.

GNU Radio is a signal-processing package and part of the GNU Project. It is distributed under the terms of the GNU General Public License (GPL), and most of the project code is copyrighted by the Free Software Foundation^[2]

History[edit]

Gnu Companion Download Windows 10

First published in 2001, GNU Radio is an official GNU package. Philanthropist John Gilmore initiated GNU Radio with the funding of $320,000 (US) to Eric Blossom for code creation and project-management duties.

GNU Radio began as a fork of the Pspectra code that was developed by the SpectrumWare project at the Massachusetts Institute of Technology (MIT). In 2004, a complete rewrite of GNU Radio was completed, so today GNU Radio no longer has any original Pspectra code. Also of note is that the Pspectra codebase has been used as the foundation of the commercial Vanu Software Radio.

Matt Ettus joined the project as one of the first developers, and created the Universal Software Radio Peripheral (USRP) to provide a hardware platform for use with the GNU Radio software.

In September 2010, Eric Blossom stepped down as Project Lead and was replaced by Tom Rondeau.^[3]/universe-sandbox-2-download-mac.html. Pixlr o matic download mac.

Early in the project, the core developers began holding semi-annual Hackfests. In 2011, the GNU Radio project began holding a yearly conference, called 'GRCon', which generally has a Hackfest on the last day of the conference.

In March 2016, Tom Rondeau stepped down and was replaced by Ben Hilburn as the Project Lead, and Johnathan Corgan, a long-time maintainer, as the Chief Architect.^[4]

In January 2018, Johnathan Corgan retired from his role in GNU Radio and was replaced by Marcus Müller.^[5]

Software[edit]

GNU Radio Companion[edit]

The GNU Radio Companion is a graphical UI used to develop GNU Radio applications.^[6] This is the front-end to the GNU Radio libraries for signal processing. GRC was developed by Josh Blum during his studies at Johns Hopkins University (2006-2007), then distributed as free software for the October 2009 Hackfest. Starting with the 3.2.0 release, GRC was officially bundled with the GNU Radio software distribution.

GRC is effectively a Python code-generation tool. When a flowgraph is 'compiled' in GRC, it generates Python code that creates the desired GUI windows and widgets, and creates and connects the blocks in the flowgraph.

GRC currently supports GUI creation using the Qt toolkit.

Plotting and displays[edit]

GNU Radio provides many common plotting and data visualization data sinks, including FFT displays, symbol constellation diagrams, and scope displays. These are commonly used both for debugging radio applications and as the user-interface to a final application.

PyBOMBS[edit]

Many users create 'out-of-tree modules' for use with GNU Radio. To manage these, and the dependencies required to run GNU Radio, the organization created the PyBOMBS (Python Build Overlay Managed Bundle System) project.^[7]

Introduction

Gnu Radio Companion

It can be a pain to correctly install GNU radio with the appropriate hardware drivers on a Windows or Mac OSX computer. Luckily, there is an alternative. Arguably, the fastest and easiest way to use GNU radio on any PC is to use a bootable USB stick with the GNU Radio Live SDR Environment (liveSDR image). The idea is that instead of permanently installing GNU Radio (as well as the supporting drivers and third party software) on a specific computer, you simply boot it from a portable USB flash drive, which contains Ubuntu Linux and all the necessary SDR software pre-installed. You can then run GNU Radio on any computer, so long as you can boot it from the USB flash device.

Below are the steps for creating a bootable USB stick with the GNU Radio Live SDR Environment.

Instructions

Download Gnu Radio Companion

1. Start with a USB flash drive with at least 8 GB of memory. Not all flash drives are created equal. From what I've read (on the Internet), some models are actually 'better' for BIOS booting compatibility than others. The basic rule of thumb is 'you get what you pay for'. So generally, you want to start with a good quality USB. Personally, however, I've had good luck with inexpensive USB sticks. For more information on this, look up 'Recommended USB Linux flash drives'.
2. Format the drive with the FAT32 file system. You can do this using Windows or MAC. This is a simple step and there are many tutorials out there for doing this. Look up 'how to format FAT32', and follow the instructions.
3. Download to your desktop the latest current stable release of The GNU Radio Live SDR Environment. This is an ISO image file. At the time of this writing, the latest release was named: ubuntu-14.04.3-desktop-amd64-gnuradio-3.7.9.iso. However, depending on when you read this, your version will most likely be updated.
4. If using Windows, download the latest version of Universal USB Installer (UUI). You can download it from here. Note: there are tons of software packages out there to create live bootable USB drives out there. I found UUI to to be the best 'first try' software package for this task.
   • After downloading and installing UUI, use it to install the The GNU Radio Live SDR Environment ISO image to your USB flash drive. UUI will ask you to select a .iso file. Select ISO image you downloaded to your desktop in the previous step. For convenience, you can also choose 1000 to 2000 MB of persistant file size. Persistence is the space on your USB drive that stores information, so that that information is still there after a reboot. Without persistance, every file you save on the USB drive is wiped clean after a reboot.
5. If using MAC OSX, you can use Unetbootin to create your live bootable USB drive. In my experience, Unetbootin works OK, but unfortunately creates USB drives that do not boot on some computers (I don't know why). So, if possible, go with UUI and Windows over Unetbootin and Mac OSX.
6. You are ready to boot! Restart your computer and boot from the USB drive. For many PC's this involves pressing F12 when you first turn it on (for my Acer laptop, I press F12 when I fist see the Acer logo after a restart). For Mac this generally involves restarting the computer and pressing the option key upon hearing the startup chime. If you are having trouble booting from the USB, you may need to change your BIOS settings.
7. If all worked well, you will be running Ubuntu. There will be an icon for GNU radio right on the desktop waiting fo you!
8. What if there is a problem and the USB just won't boot (like it freezes at the startup)? In this case, I suggest using Rufus to create your bootable USB drive (instead of UUI or Unetbootin). Rufus works excellent. The only problem with Rufus is that it does not have an option for persistence (so you will not be able to save your work on the bootable USB). Good luck!
