This book describes the fundamentals of THz communications, spanning the whole range of applications, propagation and channel models, RF transceiver technology, antennas, baseband techniques, and networking interfaces. The requested data rate in wireless communications will soon reach from 100 Gbit/s up to 1 Tbps necessitating systems with ultra-high bandwidths of several 10s of GHz which are available only above 200 GHz. In the last decade, research at these frequency bands has made significant progress, enabling mature experimental demonstrations of so-called THz communications, which are thus expected to play a vital role in future wireless networks. In addition to chapters by leading experts on the theory, modeling, and implementation of THz communication technology, the book also features the latest experimental results and addresses standardization and regulatory aspects. This book will be of interest to both academic researchers and engineers in the telecommunications industry.
Terahertz (THz) systems are seen as an enabling technology for terabits per second (Tbps) wireless communications. Whereas the first two decades of research on THz communications have primarily focused on RF aspects, namely, channel characterization and the development of components for the RF front-ends, more recent research is emerging on baseband, multiple access, and networking aspects, as potential applications have to be demonstrated. Demanding requirements on baseband processing, multiple access, and networking are coming not only from the use of ultrahigh carrier frequencies but also from the ultrahigh data rates in the Tbps regime. This will require new concepts in analogue-to-digital conversion and bring the focus to implementation efficiency, implementation cost, and power consumption, which are of key relevance for the development of forward error correction schemes. Initial access and beam tracking as key elements in THz communications will require new MAC concepts. All these aspects are covered in Chaps. 28, 29, 30 and 31.
