QualityofServiceProvisioning.rar - —One of themajor challenges in supportingmultimedia
services over Internet protocol (IP)-based code-division mul-
tiple-access (CDMA) wireless networks is the quality-of-service
(QoS) provisioning with effi cient resource utilization. Compared
with the circuit-switched voice service in the second-generation
CDMA systems (i.e., IS-95), heterogeneous multimedia applica-
tions in future IP-based CDMA networks require more complex
QoS provisioning and more sophisticated management of the
scarce radio resources. This paper provides an overview of the
CDMA-related QoS provisioning techniques in the avenues of
packet scheduling, power allocation, and network coordination,
summarizes state-of-the-art research results, and identifi es further
research issues.,2009-08-20 18:11:23,下载22次
0750677295.rar - In this communication we review some recent advances in aggregate-functions approaches, that are based on the
construction of efficient MoM basis functions by suitably grouping standard (e.g. Rao-Wilton-Glisson, RWG)
functions. The application domains, objectives and related means of achieving them can be significantly different for
the various embodiments of the aggregate-functions concept. Compressive approaches can reduce the degrees of
freedom of the problem up to allowing a direct, iteration-free solution non-compressive multiscale approaches can act
as effective pre-conditioners for iterative methods. For this reason aggregate-functions are well suited to solve antenna,
EMC and scattering problems involving large and complex objects. ,2009-08-20 16:31:26,下载21次
1420061453.rar - This book is a result of my experience as a student of electromagnetics and as a
developer of computational electromagnetics codes. My walk down this path began
early with my interest in the power of the computer, as well as the mysteries behind
radio waves and antennas. I received my fi rst real introduction to electromagnetics as
an undergraduate student at Auburn University, and my professor Thomas Shumpert
encouraged me to pursue the subject at the graduate level. ,2009-08-20 16:17:17,下载7次
076459611X.rar - Books of this nature are tremendously difficult to write.Without support from
Google (we didn’t ask, admittedly) and with Gmail being in perpetual Beta
throughout the writing process, we often found ourselves with chapters being
made obsolete overnight. Deadlines passed, were rescheduled, passed again.
Editors wept salt tears. Publishers, that sainted breed, were patient and handsome
and generally lovely. Chris Webb and Brian Herrmann, both of the Wiley clan,
stood by the project so faithfully that their names will be forever legend.Men of
the Far North will sing songs to their honor. Justin Blanton, the technical editor,
managed to combine a Law Degree with the task: there’s not enough beer in the
world to pay him back.Thanks to all of them, and everyone else at Wiley.,2009-08-20 16:10:07,下载3次
0071380604.rar - This book is a crash course about broadband technology and
services. It is not a textbook. The book lays a foundation o
understanding about what broadband is and what it is not. I
will not cover every broadband technology, but will address the
popular and up-and-coming broadband technologies.
Those who should be reading this book include: the tech
nologist who does not understand what broadband is and need
a working understanding of the technology and issues involved
and the businessman seeking to understand where investmen
dollars are going. The junior or mid-level engineer seeking a
detailed view of broadband will have to shop for the specific
book that will cover the specific technology of interest.
The book provides the tools needed to understand the
broadband industry as well as giving a background on broad
band so that an educational foundation can be established.,2009-08-20 16:08:43,下载2次
