Digital terrestrial television broadcasting (DTTB, also known as Digital Terrestrial Television, DTT) is one of the most important ways to deliver digital TV signals over the air in the VHF/UHF band, and is now under massive deployment worldwide. Written by a team of experts, this book will serve as a comprehensive guide for engineering students and practicing professionals in this area

Digital Terrestrial Television Broadcasting covers the fundamentals on channel coding and modulation technologies with emphasis on those used in DTTB systems, from the general concept to the detailed analysis, receiver design and implementation. It introduces the Single Frequency Network (SFN) as well as the multiple-input-multiple-output concept for DTTB network planning and the measurement (including methodology and performance) of DTTB systems using Digital Terrestrial/Television Multimedia Broadcasting (DTMB) system as an example before introducing various mobile multimedia DTV systems based on DTTB networks. Important features of this book include:

• General techniques for digital terrestrial TV broadcasting receiver design such as carrier synchronization, timing recovery, channel estimation, equalization, decoding, and de-interleaving with concrete implementation details
• Key topics for the understanding of DTTV systems: frame structure, modulation, error correction, and channel coding
• An introduction to the latest announced systems such as ATSC M/H and DVB-NGH

The editors of this book are leading experts in the field and are actively involved in the Chinese national standard on the digital terrestrial television broadcasting activities.
