Software Receiver Design: Build your Own Digital Communication System in Five Easy Steps
Have you ever wanted to know how modern digital communications systems work? Find out with this step-by-step guide to building a complete digital radio that includes every element of a typical, real-world communication system. Chapter by chapter, you will create a MATLAB realization of the various pieces of the system, exploring the key ideas along the way, as well as analyzing and assessing the performance of each component. Then, in the final chapters, you will discover how all the parts fit together and interact as you build the complete receiver. In addition to coverage of crucial issues, such as timing, carrier recovery and equalization, the text contains over 400 practical exercises, providing invaluable preparation for industry, where wireless communications and software radio are becoming increasingly important. A variety of extra resources are also provided online, including lecture slides and a solutions manual for instructors.
Why Read This Book
You will get a practical, example-driven path to building a full software-defined receiver in MATLAB, learning the implementation details behind timing recovery, carrier synchronization, equalization and performance measurement. The book combines clear explanations with hundreds of exercises and ready-to-run MATLAB code so you can experiment and see how each block behaves under realistic channel conditions.
Who Will Benefit
Engineers and graduate students who know basic signals and communications and want a hands-on, MATLAB-based guide to implementing and testing real-world digital receivers.
Level: Intermediate — Prerequisites: Basic signals & systems and digital communications concepts, undergraduate-level probability, linear algebra, and working familiarity with MATLAB.

How It Compares
More hands-on and MATLAB-centric than Proakis' Digital Communications (which is theory-heavy); complements modern SDR texts (e.g., Software Defined Radio for Engineers) by focusing on stepwise MATLAB implementations and classroom-ready exercises.
