Noncoherent Ultra Wideband Wireless Sensor Networks for Primary User Detection
(IEEE Computer Society, 2016)
As a result of increasing demand for new technologies unlicensed usage of available spectrum has become very essential to provide an efficient usage of spectrum. For that reason sensor networks may be a reliable option to ...
On Channel Estimation in DC Biased Optical OFDM Systems Over VLC Channels
(IEEE Computer Society, 2016)
Visible Light Communication(VLC) has been considered as a potential access option for 5G wireless systems to solve performance limitation due to bandwidth shortage at radio frequency (RF) band. In (VLC) system illumination ...
Traditional Folklore Forms in Temaşa-i Dünya ve Cefakar-u Cefakeş [Temaşa-i Dünya ve Cefakar-u Cefakeş´te Geleneksel Folklor Biçimleri]
(Milli Folklor Dergisi, 2016)
Temaşa-i Dünya ve Cefakâr u Cefakeş written by Evangelinos Misailidis in 1871-1872 has widely been considered to be an adaptation of the Greek novel O Polipathis (1839) and its originality has not been adequately emphasized ...
Corporations as Diplomatic Actors: Conceptualizing International Communication Tools
(IGI Global, 2016)
This chapter presents a theoretical look on the available international communication tools that can be used by multinational corporations (MNCs) to engage in diplomatic relations. Specifically, the chapter will provide ...
Branding cities in the age of social media: A comparative assessment of local government performance
(Springer International Publishing, 2015)
This chapter is a comparative study of how three local governments- Cape Town (South Africa) Philadelphia (Pennsylvania USA) and Myrtle Beach (South Carolina USA)-use social media platforms in their city branding attempts. ...
Optical OFDM with index modulation for visible light communications
(Institute of Electrical and Electronics Engineers Inc., 2015)
In this paper we propose optical orthogonal frequency division multiplexing with index modulation (O-OFDM-IM) for visible light communications (VLC) systems employing light emitting diodes (LEDs) and photodetectors (PDs). ...
Iterative channel estimation and decoding of turbo coded SFBC-OFDM systems
(IEEE, 2007)
We consider the design of turbo receiver structures for space-frequency block coded orthogonal frequency division multiplexing (SFBC-OFDM) systems in the presence of unknown frequency and time selective fading channels. ...
Thermal rearrangement of 2-acetoxy-266-trimethylbicyclo[3.1.0]hexane: Theoretical elucidation of the mechanism
(Elsevier Science, 2007)
Bicyclohexenes are believed to be the immediate precursors of aromatic compounds. As a part of the exploratory study of thermal aromatization reactions 266-trimethylbicyclo[3.1.0]hexan-2-ol and its ester derivative ...
An Integrated Software Architecture for Bandwidth Adaptive Video Streaming
(World Acad Sci Eng & Tech-Waset, 2008)
Video streaming over lossy IP networks is very important issues due to the heterogeneous structure of networks. Infrastructure of the Internet exhibits variable bandwidths delays congestions and time-varying packet losses. ...
Design of practical matching networks with lumped elements via modeling
(IEEE, 2007)
It is a common practice to utilize commercially available software tools to design matching networks for wireless communication systems. Most of these tools require a properly selected matching network topology with good ...
