Tags: sdr software-defined-radio signal-processing dsp radio communications

Install: brew install gnuradio

About:
GNU Radio is a free and open-source software development toolkit that provides signal processing blocks to implement software-defined radios and signal processing systems. It allows users to create complex radio applications using Python or C++ without needing deep hardware knowledge. The platform serves as a comprehensive framework for building real-time, high-performance signal processing flows.

Key Features:

Visual signal flowgraph construction with GNU Radio Companion
Extensive library of signal processing blocks
Python and C++ APIs for flexible development
Hardware agnostic interface supporting SDRs and custom devices
Live signal analysis and spectrum visualization tools

Use Cases:

Building custom software-defined radio (SDR) applications
Digital signal processing algorithm prototyping and research
RF spectrum monitoring and analysis systems
Educational tool for teaching DSP and communications engineering

Alternatives:

sdrangel – More GUI-focused SDR application, less programmable than GNU Radio's flowgraph approach
liquid-dsp – Lightweight DSP library for embedded systems, lacks GNU Radio's visual development environment
