ABSTRACT

In the last years one of the main technological efforts in satellite communications is the integration of digital broadcast services with two-way communications: this is justified by the research of new business perspective and in the increase of technological efficiency.
Traditionally, common air interface (CAI) standards have been rigorously defined in great detail to ensure optimized operation for specific application and to permits the interoperability between the equipment of different manufactures devices. In this context, S ....etc

A Technique for Orthogonal Frequency Division Multiplexing
Frequency Offset Correction

Abstract:
The Orthogonal Frequency Division Multiplexing (OFDM) is a Multi Carrier Modulation technique employing Frequency Division Multiplexing of orthogonal subcarriers. It is also sometimes called as discrete multitone modulation (DMT). It is better than CDMA in high bit rate and Broadband Communications .It is a multi carrier technique, which is very sensitive to Frequency Offset between transmitter and receiver. Th ....etc

RF light sources follow the same principles of converting electrical power into visible radiation as conventional gas discharge lamps. The fundamental difference between RF lamps and conventional lamps is that RF lamps operate without electrodes .the presence of electrodes in conventional florescent and High Intensity Discharge lamps has put many restrictions on lamp design and performance and is a major factor limiting lamp life.

Recent progress in semiconductor power switching electronics, which is revolutionizing many facto ....etc

Radio-frequency identification


Radio-frequency identification (RFID) is the use of an object applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.

Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information, modulating and demodulating a radio-frequency (RF) signal, and other specialized functions. The second is an antenna ....etc

After years of research and development, radio frequency light sources are just now becoming a mainstream lighting option. RF light sources follow the same principles of converting electrical power into visible radiation as conventional gas discharge lamps. The fundamental difference between RF lamps is that RF lamps operate without electrodes .There are three practical ways to energize RF light sources, though there are more ways to create RF plasmas. These three ways correspond to different types of interaction of electroma ....etc

RFID systems have been sued in numerous applications like asset tracking, toll collection and libraries. The following seminar presents our on going research for the Auburn University Detection and Food Safety (AUDFS) project to use RFID technology combined with sensors for detection of pathogens in food. AUDFS aims to integrate the breakthrough in the detection of food borne illnesses with advances in wireless and biosensor technologies. The goal of the research is a system that can keep track of food products from initial production throughou ....etc
