GNU Radio is a collection of software that when combined with minimal hardware, allows the construction of radios where the actual waveforms transmitted and received are defined by software.
What this means is that it turns the digital modulation schemes used in today's high performance wireless devices into software problems. Joe Mitola says, "A software radio is a radio whose channel modulation waveforms are defined in software. That is, waveforms are generated as sampled digital signals, converted from digital to analog via a wideband DAC and then possibly upconverted from IF to RF.
The receiver, similarly, employs a wideband Analog to Digital Converter ADC that captures all of the channels of the software radio node. The receiver then extracts, downconverts and demodulates the channel waveform using software on a general purpose processor. For our purposes, on the receive side, the idea is to get a wide band ADC as close to the antenna as is convenient, get the samples into something we can program, and then grind on them in software.
