GNU Radio for Advanced SDR Development

Build a deeper understanding of GNU Radio and develop the skills to create custom software-defined radio applications.

Connecting signal processing blocks is only part of SDR development. Building a reliable radio application also requires an understanding of sample rates, synchronization, hardware limitations, software architecture, and performance measurement.

GNU Radio for Advanced SDR Development connects these subjects in a practical guide for programmers, electronics professionals, researchers, and engineers ready to work beyond introductory radio tutorials.

Declan Ross explains how digital signal processing concepts translate into GNU Radio implementations, helping you understand the reasoning behind your design choices and the factors that affect their results.

Inside, you will learn how to:

• Work with GNU Radio architecture, scheduling, buffers, stream tags, and message passing.
• Process complex I/Q signals using digital filters, resampling, and polyphase channelizers.
• Account for SDR hardware constraints, gain settings, frequency error, DC offset, and I/Q imbalance.
• Structure Python applications and develop custom processing blocks with C++ and out-of-tree modules.
• Understand digital modulation, symbol timing, carrier recovery, equalization, and packet processing.
• Design OFDM signal chains and evaluate their behavior under noise and multipath.
• Measure communication performance using bit error rate, error vector magnitude, and repeatable signal tests.
• Address hardware timing, multi-device synchronization, external software integration, and headless deployment.

The explanations combine engineering theory, equations, code examples, and practical implementation considerations. Throughout the book, attention stays on how software decisions interact with physical radio behavior.

Written for readers with programming experience and a foundation in electronics, this guide develops the technical understanding needed to make informed choices when building, testing, and maintaining SDR systems.

Move beyond basic flowgraphs and approach GNU Radio development with greater precision, structure, and confidence.
