Synchronization in Digital Communication Systems
Do you need to know how to develop more efficient digital communication systems? Based on the author's experience of over thirty years in industrial design, this practical guide provides detailed coverage of synchronization subsystems and their relationship with other system components. Readers will gain a comprehensive understanding of the techniques needed for the design, performance analysis and implementation of synchronization functions for a range of different modern communication technologies. Specific topics covered include frequency-looked loops in wireless receivers, optimal OFDM timing phase determination and implementation, and interpolation filter design and analysis in digital resamplers. Numerous implementation examples help readers to develop the necessary practical skills, and slides summarizing key concepts accompany the book online. This is an invaluable guide and essential reference for both practicing engineers and graduate students working in digital communications.
Why Read This Book
You will learn how to design, analyze, and implement robust synchronization subsystems that are central to modern digital communication receivers. The book pairs thirty years of industrial practice with clear treatment of PLL/FLL, OFDM timing, interpolation resamplers and implementation examples so you can move from theory to working receiver blocks quickly.
Who Will Benefit
Engineers and system designers with some DSP/communications background who need practical methods to build and optimize synchronization blocks for wireless, OFDM and SDR receivers.
Level: Advanced — Prerequisites: Undergraduate-level signals and systems, basic digital communications (complex baseband, symbol concepts), digital signal processing (sampling, filtering, FFT), and familiarity with MATLAB or equivalent simulation tools.

How It Compares
Compared with Mengali & D'Andrea's 'Synchronization Techniques for Digital Receivers', this book is more implementation- and industry-focused with updated coverage of OFDM timing and interpolation resamplers; compared with Proakis' 'Digital Communications', it is narrower but much deeper on practical synchronization subsystems.
