Starting Digital Signal Processing in Telecommunication Engineering, 1st ed. 2021
A Laboratory-based Course
Textbooks in Telecommunication Engineering Series

This hands-on, laboratory driven textbook helps readers understand principles of digital signal processing (DSP) and basics of software-based digital communication, particularly software-defined networks (SDN) and software-defined radio (SDR). In the book only the most important concepts are presented. Each book chapter is an introduction to computer laboratory and is accompanied by complete laboratory exercises and ready-to-go Matlab programs with figures and comments (available at the book webpage and running also in GNU Octave 5.2 with free software packages), showing all or most details of relevant algorithms. Students are tasked to understand programs, modify them, and apply presented concepts to recorded real RF signal or simulated received signals, with modelled transmission condition and hardware imperfections. Teaching is done by showing examples and their modifications to different real-world telecommunication-like applications. The book consists of three parts: introduction to DSP (spectral analysis and digital filtering), introduction to DSP advanced topics (multi-rate, adaptive, model-based and multimedia - speech, audio, video - signal analysis and processing) and introduction to software-defined modern telecommunication systems (SDR technology, analog and digital modulations, single- and multi-carrier systems, channel estimation and correction as well as synchronization issues).

Many real signals are processed in the book, in the first part ? mainly speech and audio, while in the second part ? mainly RF recordings taken from RTL-SDR USB stick and ADALM-PLUTO module, for example captured IQ data of VOR avionics signal, classical FM radio with RDS, digital DAB/DAB+ radio and 4G-LTE digital telephony. Additionally, modelling and simulation of some transmission scenarios are tested in software in the book, in particular TETRA, ADSL and 5G signals.?

• Provides an introduction to digital signal processing and software-based digital communication;
• Presents a transition from digital signal processing to software-defined telecommunication;
• Features a suite of pedagogical materials including a laboratory test-bed and computer exercises/experiments??.

Tomasz P. Zielinski received the M.S. degree in electronics, the D.Sc. degree (habilitation) in electrical engineering and the scientific Professor title in telecommunications from the AGH University of Science and Technology (AGH-UST), Kraków, Poland, in 1982, 1996 and 2003, respectively, and the Ph.D. degree in electrical engineering from the Institute of Engineering Cybernetics and Robotics of Bulgarian Academy of Sciences, Sofia, Bulgaria, in 1988. Since 1982 he has been working at the Department of Instrumentation & Measurement AGH-UST as a Research & Teaching Assistant (1982), Associate (1989), Assistant Professor (1996) and Associate Professor (2000). In 2006 he joined the Department of Telecommunications, AGH-UST as a Full Professor. He has authored and co-authored more than 175 scientific journal and conference papers. He is also the author of three monographs (all in Polish): Time-Frequency and Time-Scale Representations of Non-stationary Signals (1996), From Theoryto Digital Signal Processing (2002, 2004) and Digital Signal Processing: From Theory to Applications (2005, 2007, 2009), as well as the main editor and the co-author of the Polish book Digital Signal Processing in Telecommunications – Fundamentals. Multimedia. Transmission (2014). He has been a supervisor of more than 10 Polish research projects and actively participated in a few international programs (EPSR Council UK, ECSON: Engineering and Computational Science for Oncology Network; VECTOR EC FP6: Versatile Endoscopic Capsule for gastrointestinal TumOr Recognition and therapy; NIH, USA: “Efficacy of Laryngeal High-Speed Video-endoscopy”). His research interests include advanced digital signal processing in telecommunication and biomedical systems, especially time-frequency signal analysis. He is an IEEE member.
