ABSTRACT
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.

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

The most important development in the computer communications industry in the 1990s is the evolution of the integrated services digital network (ISDN) and broadband ISDN (B-ISDN). The ISDN and B-ISDN have had a dramatic impact on the planning and deployment of intelligent digital networks providing integrated services for voice, data and video. Further, the work on the ISDN and B-ISDN standards has led to the development of two major new networking technologies; frame relay and asynchronous transfer mode (ATM). Frame relay and ATM ....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
