书籍 IP,+Ethernet+and+MPLS+Networks+
This book addresses two aspects of network operation quality; namely, resource
management and fault management.
Network operation quality is among the functions to be fulfilled in order to offer
quality of service, QoS, to the end user. It is characterized by four parameters:
– packet loss;
– dela ...
书籍 MIMO+Broadcast+Channel
Due to the asymmetry between the amount of data traffic in the downlink and
uplink direction of nowadays and future wireless networks, a proper design of the
transceivers in the broadcast channel is inevitable in order to satisfy the users’
demands on data rate and transmission quality. This book d ...
书籍 Opportunistic+Spectrum+Sharing
Rapid growth of wireless communication services in recent decades has created
a huge demand of radio spectrum. Spectrum scarcity and utilization inefficiency
limit the development of wireless networks. Cognitive radio is a promising tech-
nology that allows secondary users to reuse the underutilized ...
书籍 QOS-Enabled Networks
Quality of Service ( QoS ) has always been in a world of its own, but as the technology
has been refi ned and has evolved in recent years, QOS usage has increased to the point
where it is now considered a necessary part of network design and operation. As with
most technologies, large - scale deploy ...
书籍 Radio+Protocols+for+LTE+and+LTE-A
It was only a few years ago that “ubiquitous connectivity” was recognized as the future of
wireless communication systems. In the era of ubiquitous connectivity, it was expected that
the broadband mobile Internet experience would be pervasive, and seamless connectivity on
a global scale would be n ...
书籍 Space-Time+Processing
Driven by the desire to boost the quality of service of wireless systems closer to that afforded
by wireline systems, space-time processing for multiple-input multiple-output (MIMO)
wireless communications research has drawn remarkable interest in recent years. Excit-
ing theoretical advances, compl ...
书籍 Transmission Techniques for 4G Systems
Fourth Generation (4G) wireless communication systems aim to allow peak data
rates in the range of 1 Gbps for nomadic access and 100 Mbps for vehicular mobil-
ity. 4G aims to support current and emergent multimedia services, such as mobile
TV, social networks and gaming, high-definition television a ...
书籍 UMTS+Performance+Measurement+A+Practical+Guide
Having dealt with in-depth analysis of SS#7, GSM and GPRS networks I started to monitor
UTRAN interfaces approximately four years ago. Monitoring interfaces means decoding
the data captured on the links and analysing how the different data segments and messages
are related to each other. In general ...
技术资料 Understanding_the_Basics_of_MIMO
An acronym for Multiple-In, Multiple-Out, MIMO communication sends the same data as several signals
simultaneously through multiple antennas, while still utilizing a single radio channel. This is a form of
antenna diversity, which uses multiple antennas to improve signal quality and strength of an R ...
书籍 WCDMA for UMTS HSPA Evolution and LTE
Second-generation telecommunication systems, such as the Global System for Mobile
Communications (GSM), enabled voice traffic to go wireless: the number of mobile phones
exceeds the number of landline phones and the mobile phone penetration is approaching
100% in several markets. The data-handling c ...
