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, Gnuradio1 is now one of the official projects of GNU. Philanthropist John Gilmore initiated and donated $320000.00 (US) to Eric Blossom to build code and maintain.
Gnuradio is a radio signal processing scheme, which is distributed according to the GPL terms of GNU. Its purpose is to provide ordinary software developers with the opportunity to explore electromagnetic waves, and stimulate their ability to use RF waves intelligently.
As all software defined radio systems are defined, reconfigurability is their most important function. There is no need to buy a lot of transmitting and receiving equipment, as long as a device that can load signal processing software (here: Gnuradio). At present, it only defines a few limited radio functions, but as long as you understand the mechanism (algorithm) of the wireless transmission system, you can accept it in any configuration.
Gnuradio originated from the branch of Psctra code developed by the Spectrum Ware project team of Massachusetts Institute of Technology in the United States. It was completely rewritten in 2004. So today's Gnuradio does not contain any code of the original Psctra. In addition, it is worth mentioning that Pspectra has been used to create a commercial Vanu Software Radio
Gnuradio has developed general software radio peripherals (USRP and USRP2). It is a 12 bit ADC with four 64 MS/s, a 14 bit DAC with four 128 MS/s, and other supporting lines, including high-speed USB 2.0 interfaces. The USRP can process signals up to 16 MHz wide. Some transmitter and receiver plug-in daughter boards can cover the 0 to 5.9MHz frequency band. It was developed by Ettus.

Introduction to GNU Radio and Software Radio

What is GNU Radio?

GNU Radio is a framework that enables users to design, simulate, and deploy highly capable real-world radio systems. It is a highly modular, “flowgraph”-oriented framework that comes with a comprehensive library of processing blocks that can be readily combined to make complex signal processing applications.
GNU Radio has been used for a huge array of real-world radio applications, including audio processing, mobile communications, tracking satellites, radar systems, GSM networks, Digital Radio Mondiale, and much more – all in computer software.
It is, by itself, not a solution to talk to any specific hardware. Nor does it provide out-of-the-box applications for specific radio communications standards (e.g., 802.11, ZigBee, LTE, etc.,), but it can be (and has been) used to develop implementations of basically any band-limited communication standard.

Why would I want GNU Radio?

Formerly, when developing radio communication devices, the engineer had to develop a specific circuit for detection of a specific signal class, design a specific IC that would be able to decode or encode that particular transmission and debug these using costly equipment.
Software-Defined Radio (SDR) takes the analog signal processing and moves it, as far as physically and economically feasible, to processing the radio signal on a computer using algorithms in software.
You can, of course, use your computer-connected radio device in a program you write from scratch, concatenating algorithms as you need them and moving data in and out yourself. But this quickly becomes cumbersome: Why are you re-implementing a standard filter? Why do you have to care how data moves between different processing blocks? Wouldn’t it be better to use highly optimized and peer-reviewed implementations rather than writing things y ourself? And how do you get your program to scale well on a multi-core architectures but also run well on an embedded device consuming but a few watts of power?
Enter GNU Radio: A framework dedicated to writing signal processing applications for commodity computers. GNU Radio wraps functionality in easy-to-use reusable blocks, offers excellent scalability, provides an extensive library of standard algorithms, and is heavily optimized for a large variety of common platforms. It also comes with a large set of examples to get you started.

Digital Signal Processing

As a software framework, GNU Radio works on digitized signals to generate communication functionality using general-purpose computers.

A little signal theory
Doing signal processing in software requires the signal to be digital. But what is a digital signal?
To understand better, let’s look at a common “signal” scenario: Recording voice for transmission using a cellphone.
A personal physically speaking creates a sound ‘signal’ – the signal, in this case, is comprised of waves of varying air pressure being generated by the vocal chords of a human. A time-varying physical quantity, like the air pressure, is what is defined as a signal.

Applying Digital Signal Processing to Radio Transmissions
The same principles as for sounds can be applied to radio waves:
A signal, here electromagnetic waves, can be converted into a varying voltage using an antenna.

A modular, flowgraph based Approach to Digital Signal Processing

GNU Radio is a framework to develop these processing blocks and create flowgraphs, which comprise radio processing applications.
As a GNU Radio user, you can combine existing blocks into a high-level flowgraph that does something as complex as receiving digitally modulated signals and GNU Radio will automatically move the signal data between these and cause processing of the data when it is ready for processing.GNU Radio comes with a large set of existing blocks. Just to give you but a small ex cerpt of what’s available in a standard installation, here’s some of the most popular block categories and a few of their members:
Waveform Generators

• Constant Source
• Noise Source
• Signal Source

Modulators

• AM Demod
• Continuous Phase Modulation
• PSK Mod / Demod
• DPSK Mod / Demod
• GMSK Mod / Demod
• QAM Mod / Demod
• WBFM Receive
• NBFM Receive

Instrumentation

• Constellation Sink
• Frequency Sink
• Histogram Sink
• Number Sink
• Time Raster Sink
• Time Sink
• Waterfall Sink

Math Operators

• Abs
• Add
• Complex Conjugate
• Divide
• Integrate
• Log10
• Multiply
• RMS
• Subtract

Channel Models

• Channel Model
• Fading Model
• Dynamic Channel Model
• Frequency Selective Fading Model

Filters

• Band Pass / Reject Filter
• Low / High Pass Filter
• IIR Filter
• Generic Filterbank
• Hilbert
• Decimating FIR Filter
• Root Raised Cosine Filter
• FFT Filter

Fourier Analysis

• FFT
• Log Power FFT
• Goertzel (Resamplers)
• Fractional Resampler
• Polyphase Arbitrary Resampler
• Rational Resampler (Synchronizers)
• Clock Recovery MM
• Correlate and Sync
• Costas Loop
• FLL Band-Edge
• PLL Freq Det
• PN Correlator
• Polyphase Clock Sync

Using these blocks, many standard tasks, like normalizing signals, synchronization, measurements, and visualization can be done by just connecting the appropriate block to your signal processing flow graph.
Also, you can write your own blocks, that either combine existing blocks with some intelligence to provide new functionality together with some logic, or you can develop your own block that operates on the input data and outputs data.
Thus, GNU Radio is mainly a framework for the development of signal processing blocks and their interaction. It comes with an extensive standard library of blocks, and there are a lot of systems available that a developer might build upon. However, GNU Radio itself is not a software that is ready to do something specific — it’s the user’s job to build something useful out of it, though it already comes with a lot of useful working examples. Think of it as a set of building blocks.
