Beyond-3G.rar - This paper defines the requirements for cooperation of heterogeneous radio
access networks (RANs) and proposes a novel radio resource management (RRM) framework
for support of mobility and quality of service (QoS) in a heterogeneous communication
environment comprising IMT-Advanced and legacy systems. The reference IMT-Advanced
system is the one developed within the IST projectWINNER(IST-2003-507581 ProjectWireless
Initiative New Radio, http://www.ist-winner.org). The RRM mechanisms are evolved
from traditional ones to comply with the requirements imposed by a simplified new (RAN)
architecture as proposed for IMT-Advanced systems. The RRM mechanisms are evaluated
for the scenario of intra-RAN and inter-RAN user mobility. The RRM framework incorporates
as novelty improved triggering mechanisms, a network-controlledmobility management
scheme with policy enforcement on different levels in the RANarchitecture, and a distributed,2011-08-19 12:45:02,下载8次
location-based-services.rar - This paper presents a technique which is based on pattern recognition techniques, in order to estimate
Mobile Terminal (MT) velocity. The proposed technique applies on received signal strength (RSS) measurements
and more precisely on information extracted from Iub air interface, in wideband code-division multiple access
(WCDMA) systems for transmission control purposes. Pattern recognition is performed by Hidden Markov Model
(HMM), which is trained with downlink signal strength measurements for specific areas, employing Clustering
LARge Applications (CLARA) like a clustering method. Accurate results from a single probe vehicle show the
potential of the method, when applied to large scale of MTs.,2011-08-19 12:41:15,下载13次
space-time-block-coding.rar - An adaptive transmit diversity scheme with quadrant phase constraining feedback is proposed in this
paper. With simple linear operations at both transmitter and receiver, the proposed algorithm can achieve better
system performances with only 2M − 2 bits of feedback information for systems with M transmit antennas.
Theoretical performance bounds of the proposed transmit diversity scheme are derived. Simulation examples and
theoretical analyses show that the proposed transmit diversity scheme outperforms not only the conventional openloop
transmit diversity techniques, but also some closed-loop transmit diversity techniques with more information
transmitted in the feedback channel.,2011-08-19 12:39:33,下载4次
WCDMA.rar - In WCDMA networks, the presence of a cell is announced through a common pilot
channel (CPICH). The power levels of the pilot channels have a great impact
on coverage and service quality. Using mathematical optimization techniques,
we address the problem of minimizing the amount of pilot power for providing
service coverage and smooth handover. We present numerical results for several
realistic planning scenarios of WCDMA networks, and analyze the pilot power
solutions found by optimization versus those obtained by ad hoc strategies.,2011-08-19 12:37:00,下载3次
Smart.Antennas.For.Wireless.Communications.rar - Analysis of variance (ANOVA) is a core technique for analysing data in the Life Sciences. This reference book bridges the gap between statistical theory and practical data analysis by presenting a comprehensive set of tables for all standard models of analysis of variance and covariance with up to three treatment factors. The book will serve as a tool to help post-graduates and professionals define their hypotheses, design appropriate experiments, translate them into a statistical model, validate the output from statistics packages and verify results. The systematic layout makes it easy for readers to identify which types of model best fit the themes they are investigating, and to evaluate the strengths and weaknesses of alternative experimental designs. In addition, a concise introduction to the principles of analysis of variance and covariance is provided, alongside worked examples illustrating issues and decisions faced by analysts.,2010-08-16 18:32:34,下载3次
map-based-mobile-services-theories-methods-and-im - The book is divided into three parts: theory, method and implementation. Starting with a summary of the state-of-the-art in mobile technologies, the first part analyses their impacts on cartography and pinpoints the missing theories concerned with the development of map-based mobile services. A conceptual framework of mobile cartography is then introduced with the emphasis on mobile usage context. The second part is devoted to the design methodology under the constraints defined in the theoretical framework. A core issue deals with personalised mobile map services. The final part demonstrates the feasibility of the methods by using application scenarios.,2010-08-16 18:02:35,下载3次

Wiley.Global.Positioning.Technologies.and.Perform - The field of radionavigation signals and systems has seen significant growth in recent years. Satellite systems are very efficient, but owing to their limited exposure and/or availability in some environments, they do not cover the whole spectrum of applications. Thus, many other positioning techniques are being developed.
Now, Global Positioning presents an overview of the strengths and weaknesses of various systems with a specific emphasis on those that are satellite-based. Beginning with a description of the evolution of positioning systems, the book provides detailed coverage of the three main Global Navigation Satellite System (GNSS) constellations, discusses how to cope with indoor positioning, defines development activities and commercial positioning, and proposes a vision for the future of the field.,2010-08-16 17:53:59,下载29次

IPfor3G.rar - What is an all-IP network? What difference will IP networking make to 3G services?
Third Generation (3G) mobile offers access to broadband multimedia services - and in the future most of these, even voice and video, will be IP-based. However 3G networks are not based on IP technologies, rather they are an evolution from existing 2G networks. Much work needs to be done to IP QoS and mobility protocols and architectures for them to be able to provide the functionality 3G requires.
IP for 3G gives a comprehensive overview of 3G networking functionality and examines how IP protocols can be developed to provide some of the basic building blocks of a mobile system (mobility, QoS and call control),2010-04-02 19:14:36,下载4次
