The 4.0 kbit/s speech codec described in this paper is based on a
Frequency Domain Interpolative (FDI) coding technique, which
belongs to the class of prototype waveform Interpolation (PWI)
coding techniques. The codec also has an integrated voice
activity detector (VAD) and a noise reduction capabi ...
The Universal Radio Hacker (URH) is a software for investigating unknown wireless protocols. Features include
* __hardware interfaces__ for common Software Defined Radios
* __easy demodulation__ of signals
* __assigning participants__ to keep overview of your data
* __customizable decodings__ to cr ...
The rapid growth of the Web in the past two decades has made it the larg-
est publicly accessible data source in the world. Web mining aims to dis-
cover useful information or knowledge from Web hyperlinks, page con-
tents, and usage logs. Based on the primary kinds of data used in the
mining proces ...
In recent years, cellular voice networks have transformed into powerful packet-switched
access networks for both voice communication and Internet access. Evolving Universal
Mobile Telecommunication System (UMTS) networks and first Long Term Evolution
(LTE) installations now deliver bandwidths of sev ...
Homogeneous Partitioning of the Surveillance Volume discusses the
implementation of the first of three sequentially complementary approaches for
increasing the probability of target detection within at least some of the cells of
the surveillance volume for a spatially nonGaussian or Gaussian “noise ...
One traditional view of how wireless networks evolve is of a continuous, inevitable progres-
sion to higher link speeds, combined with greater mobility over wider areas. This standpoint
certainly captures the development from first and second generation cellular systems focused
on voice support, and ...
Wireless penetration has witnessed explosive growth over the last two decades.
Accordingly, wireless devices have become much denser per unit area, resulting
in an overcrowded usage of wireless resources. To avoid radio interferences and
packet collisions, wireless stations have to exchange control ...
Emerging technologies such as WiFi and WiMAX are profoundly changing the
landscape of wireless broadband. As we evolve into future generation wireless
networks, a primary challenge is the support of high data rate, integrated multi-
media type traffic over a unified platform. Due to its ...
The idea of the book was born during the time when the second generation cellular system was looming on the horizon.At that time ,the world was divided into three distinct camps as far as looking for a standard: Europe North America and Japan.
The genesis for this book was my involvement with the development of the
SystemView (now SystemVue) simulation program at Elanix, Inc. Over several
years of development, technical support, and seminars, several issues kept recur-
ring. One common question was, “How do you simulate (such and such)? ...
