Amazon Summary
Digital Signal Processing in Modern Communication Systems takes you on a journey that starts with basic DSP principles and ends with a treatment of modern wireless modems like OFDM and single-tone transceivers. Throughout this journey, we will cover signal processing topics that are applicable not just to the field of communications but to many engineering disciplines. This text steps outside the often dry mathematical presentation of more traditional DSP books and provides a more intuitive approach to this fascinating topic. Some of this book’s uniqueness can be summarized as follows: - An intuitive approach to the topic of digital signal processing. - Working in-book MatLab examples supporting all important concepts. - A large scope covering basic concepts (correlation, convolution, DFT, FIR filters …) as well as advanced topics (optimization, adaptive signal processing, equalization, OFDM, MIMO … ). - MatLab modeling of analog/RF effects (multipath channel, thermal noise, phase noise, IQ imbalances, DC and frequency offsets) that must be addressed and solved in modern modem design. - Real world topics that go beyond the ordinary communication textbooks such as signal synchronization, modem rate management, and fixed-point effects. All in all, this book is a must-have for students and practicing engineers who want to build upon the principles of Digital Signal Processing, enrich their understanding with advanced topics, and then apply that knowledge to the design of modern wireless modems.
This is an excellent book on learning DSP for modern wireless communications and it should get you over the fundamentals [1].
There is an interesting project for open source LoRa physical layer implementation in GNU Radio. The authors had to reverse engineer the LoRa physical layer for the implementation because it is proprietary unlike the data link layer LoRaWAN part of it [2].
[1]Digital Signal Processing in Modern Communication Systems:
I/Q is really amazing and it's an offshoot of the Euler's formula.
The best book to understand I/Q if your background is not engineering is probably this book "Digital Signal Processing in Modern Communication System" by Andreas Schwarzinger [1].
This book will teach from the basic principles of communication from the I/Q up to OFDM, basically most of the essential techniques of modern communication as mentioned in its title.
