Welcome to GNU Radio!

Introduction

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 the digital modulation schemes used in today's high performance wireless devices are now software problems.
