ABSTRACT

Mankind has come across many stages right from ancient Stone Age to the modern wireless age. In every stage it developed its own unique method of communication to suit its requirements. These methods range from Graham Bell s cabled telephones to today s wireless mobile handsets. But if there could be a technology such that the waves co ....etc

UWB is a wireless technology that transmits binary data the 0s and 1s that are the digital building blocks of modern information systems. It uses low-energy and extremely short duration (in the order of pico seconds) impulses or bursts of RF (radio frequency) energy over a wide spectrum of frequencies, to transmit data over short to medium distances, say about 15 100 m. It doesn t use carrier wave to transmit data.Ultra Wide Bandwidth (UWB) can handle more bandwidth intensive applications such as streaming video than either 802.11 or Bluet ....etc

INTRODUCTION
The average person has a small home, but a huge appetite for entertainment. All of us would want to zap video images from digital camcorders to our hard drives without tripping over the cables that connect them. As home entertainment systems become more sophisticated, u will have flat panel displays. You could hang them like paintings on your wall ..Now who would want cables to dangle from those beauties
So you think - big deal . We have Bluetooth and 802.11 wireless technologies to solve this problem. Th ....etc

Abstract

A measurement campaign has been carried out in 400kV air insulated electricity substation to characterise and model radio frequency impulsive noise with a view to assessing its impact on wireless network technologies. The relatively recent availability of new technologies such as WiFi, Bluetooth and Zigbee means that particular emphasis has been put on higher frequency bands (e.g. 2.4, 5 GHz) than have previously been investigated. A detection system to measure wideband noise over a spectrum extending up to 5.1 GHz ....etc

HIGH THROUGHPUT AND LOW POWER REED SOLOMEN DECODER FOR ULTRA WIDE BAND FREQUENCIES

Abstract:- Reed Solomon (RS) codes have been widely used in a variety of communication systems such as space communication link, digital subscriber loops and wireless systems, as well as in networking Communications and magnetic and data storage systems. Continual demand for ever-higher data rates and storage capacity makes it necessary to devise very high-speed implementations of RS Decoders. Newer and faster implementations of the decoder are being developed ....etc
