In 2012 a group of researchers proposed a basic research initiative to the German Research Foundation (DFG) as a special priority project (SPP) with the name: Wireless 100 Gbps and beyond. The main goal of this initiative was the investigation of architectures, technologies and methods to go well beyond the state of the art. The target of 100 Gbps was set far away from the (at that time) achievable 1 Gbps such that it was not possible to achieve promising results just by tuning some parameters. We wanted to find breakthrough solutions. When we started the work on the proposal we discussed the challenges to be addressed in order to advancing the wireless communication speed significantly. Having the fundamental Shannon boundary in mind we discussed how to achieve the 100 Gbps speed., Angesichts der rapiden Entwicklung der Funkkommunikation hat die Deutsche Forschungsgemeinschaft im Jahr 2012 ein Schwerpunktprogramm mit dem Titel "Wireless 100 Gbps and beyound" (dt.: Drahtloskommunikation mit 100 Gbps und mehr) gestartet. Diese Initiative zielte auf neue Lösungen, Methoden und neues Wissen zur Lösung des Problems des kontinuierlichen Bedarfs an immer höheren Datenraten im Bereich der Funkkommunikation. Eine international besetze Jury hat etliche Projektvorschläge evaluiert, aus denen 11 Projekte ausgewählt und über zweimal 3 Jahre von Mitte 2013 bis Mitte 2019 gefördert wurden. Das vorliegende Buch versammelt die Ansätze, Architekturen und Erkenntnisse der Projekte. Es überspannt einen breiten Themenbereich, angefangen mit speziellen Fragen der physikalischen Übertragung, des Antennendesigns und der HF-Eingangs-Architekturen für unterschiedliche Frequenzbereiche bis 240 GHz. Darüber hinaus beschreibt das Buch Ansätze für Ultra-Hochgeschwindigkeits-Funksysteme, deren Basisbandverarbeitung, Kodierung sowie mögliche Umsetzungen. Nicht zuletzt wurden auch Fragen des Protokolldesigns behandelt, um eine enge Integration in moderne Computersysteme zu erleichtern.

In such a context, the 60 GHz band, due to the several GHz of unlicensedbandwidth worldwide, is a promising option to serve the ever-increasing demandsof local and personal area networks for higher data rates and higher spatial reuse.This dissertation’s subject is the scientific investigation of new concepts for short-range radio transceivers that work with carrier frequencies of 60 GHz and bandwidthbetween 1 and 10 GHz. For a given amount of processing energy per information bit, the overall powerconsumption increases with the data rate. When targeting data rates beyond 100Gb/s, the system’s overall power consumption soon exceeds the power which can bedissipated without forced cooling. In order to achieve a maximum data rate underthis power constraint, the processing energy per information bit must be minimized. Therefore, in this dissertation, a novel processing efficient transmission scheme, i.e., using joint analog/digital signal processing architectures, is proposed. As a pre-requisite, the wireless channel characteristics at 60 GHz are well studied, and the im-plementation of a 60 GHz channel model for system simulations is done. The majorbaseband signal processing tasks such as beamforming/MIMO techniques, channelestimation, equalization, matched filtering (pulse shaping at the transmitter) are in-vestigated. Each of the transceiver tasks is studied both concerning the high-levelpower consumption and the communication performance impact. Except that, thelow complexity algorithms with acceptable performance loss are investigated to guar-antee the strict power limit. The overall methodology is energy-driven. For instance, all design decisions liketransmission scheme selection, analog/digital partitioning, and algorithms optimiza-tion, are driven by energy efficiency. There is a strong relationship between energyefficiency and communication performance. Thus, power estimation is performed forthe components identified to be suitable for a system that meets the overall through-put, communication performance, and power constraints. This applies to compon-ents in both the analog as well as the digital part. Besides, an analysis of the relation3between energy and spectrum efficiency is also performed to guide the practical en-ergy/spectrum efficiency trade-off for the millimeter-wave system design.Finally, as proof of concept for the methodology and because of its high relevance,the proposed approach is applied towards systems operating beyond the 100 GHz car-rier frequency range. The impact of an extension to 120 GHz carrier frequency rangesand an extension from the point-to-point MIMO transmission to multi-user case areaddressed. In this dissertation, all novel designs and analytical evaluations in systemdesign aspects are validated via simulations. The results demonstrate the perform-ance advantage of millimeter wave systems, which positions 60GHz technology as acritical component in the forefront of Gbps wireless communications., Published by RWTH Aachen University, Aachen
