Announcing: Radio Systems Engineering, Revised First Edition

by Anita Walz, posted on January 8, 2024

The Open Education Initiative at Virginia Tech is pleased to announce the release of an openly-licensed, revised first edition of Radio Systems Engineering by Steven W. Ellingson.

Radio Systems Engineering, Revised First Edition is lightly updated from the version published in 2016 by Cambridge University Press (ISBN 9781107068285). While Cambridge retains rights to continue to sell and license their print and electronic versions, Cambridge has granted the author enough rights to update and release the book freely under a Creative Commons Attribution NonCommercial International License (CC BY NC 4.0).

About the Book

Using a systems framework, Radio Systems Engineering, Revised First Edition provides a clear and comprehensive introduction to the performance, analysis, and design of radio systems for students and practicing engineers. Presented within a consistent framework, the first part of the book describes the fundamentals of the subject: propagation, noise, antennas, and modulation. The analysis and design of radios including RF circuit design and signal processing is covered in the second half of the book.

“This textbook gives engineering students a complete overview of radio systems and provides practicing wireless engineers with a convenient comprehensive reference.” Patrick Roblin, Ohio State University

Key features

  • – Numerous examples within the text involve realistic analysis and design activities, and emphasize how practical experiences may differ from theory or taught procedures.
  • – RF circuit design and analysis is presented with minimal involvement of Smith charts, enabling students to more readily grasp the fundamentals.
  • – Both traditional and software-defined/direct sampling technology are described with pros and cons of each strategy explained.
