Hybrid+Analog-Digital+Precoding
In this paper we revisit hybrid analog-digital precoding systems with emphasis on their modelling<br />
and radio-frequency (RF) losses, to realistically evaluate their benefits in 5G system implement
HSDPAHSUPA+for+UMTS+High+Speed+Radio+Access
The first Third Generation Partnership Project (3GPP) Wideband Code Division<br />
Multiple Access (WCDMA) networks were launched during 2002. By the end of 2005<br />
there were 100 open WCDMA networ
GSM, GPRS and EDGE Performance Evolution
The wireless market has experienced a phenomenal growth since the first second-<br />
generation (2G) digital cellular networks, based on global system for mobile<br />
communications (GSM) technology
Green Radio Communication Networks
Currently, the information and communications technology (ICT) industry sector<br />
accounts for about 2–6% of the energy consumption worldwide, and a significant por-<br />
tion of this is contribut
Future+Mobile+Communications+LTE
Providing QoS while optimizing the LTE network in a cost efficient manner is<br />
very challenging. Thus, radio scheduling is one of the most important functions<br />
in mobile broadband networks. T
Essentials+of+Radio+Wave+Propagation
The objective of this book is to allow the reader to predict the received<br />
signal power produced by a particular radio transmitter. The first two<br />
chapters examine propagation in free space
EPC and 4G Packet Networks
The telecommunications industry is undoubtedly in a period of radical change with<br />
the advent of mobile broadband radio access and the rapid convergence of Internet<br />
and mobile services. Som
Enhanced+Radio+Access+Technologies
Following chapter introduces the mobile communication, gives a short history of wireless<br />
communication evolution, and highlights some application scenarios predestined for the<br />
use of mobil
Efficient+Methods+for+WCDMA
When joining Siemens in 2001, I also extended my research interest towards radio net-<br />
work planning methodologies. This area of research brought together my personal interest<br />
in mobile com
EDGE+for+Mobile+Internet
The General Packet Radio Service (GPRS) allows an end user to send and<br />
receive data in packet transfer mode within a public land mobile network<br />
(PLMN) without using a permanent connection
Distributed+Quality-of-Service+Support
This thesis is about wireless communication in shared radio spectrum. Its origin and<br />
motivation is ideally represented by the two quotations from above. In this thesis, the<br />
support of Qual
Digital Wireless Transceivers
The design and manufacturing of wireless radio frequency (RF) transceivers has developed rapidly in recent ten<br />
yeas due to rapid development of RF integrated circuits and the evolution of high-s
Digital Audio Broadcasting Principles
The new digital radio system DAB (Digital Audio Broadcasting, nowadays often called<br />
Digital Radio) is a very innovative and universal multimedia broadcast system which will<br />
replace the exi
Communications+Receivers
The capability of radio waves to provide almost instantaneous distant communications<br />
without interconnecting wires was a major factor in the explosive growth of communica-<br />
tions during the
Cognitive+Wireless+Network
Cognitive radio has emerged as a promising technology for maximizing the utiliza-<br />
tion of the limited radio bandwidth while accommodating the increasing amount of<br />
services and applications
Cognitive+Radio+Technology
This introduction takes a visionary look at ideal cognitive radios (CRs) that inte-<br />
grate advanced software-defined radios (SDR) with CR techniques to arrive at<br />
radios that learn to help t
