Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. [1]
The OpenHPSDR (High Performance Software Defined Radio) project dates from 2005 when Phil Covington, Phil Harman, and Bill Tracey combined their separate projects to form the HPSDR group. [1] It is built around a modular concept which encourages experimentation with new techniques and devices (e.g. SDR , Envelope Elimination and Restoration ...

The Frontier Radio is a family of software-defined radios developed by the Johns Hopkins University Applied Physics Laboratory (or APL). Four variants have been developed: the Frontier Radio (FR), the Frontier Radio Lite (FR Lite), and the Frontier Radio Multi Lingual (FR ML), and the Next-Gen Frontier Radio.
The OpenBTS Um air interface uses a software-defined radio transceiver with no specialized GSM hardware. The original implementation used a Universal Software Radio Peripheral from Ettus Research, but has since been expanded to support several digital radios in implementations ranging from full-scale base stations to embedded femtocells.

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 radio frequency (RF) hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic ...
Software-defined radio (SDR) is a radio communication system where components, that have been traditionally implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a personal computer or embedded system. [2]
