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 h ....etc

Power line communications (PLC) or Broadband over Power Lines (BPL) allows transmission of data over power lines.Power line communications uses the RF signal sent over medium and low voltage AC power lines to allow end users to connect to the Internet. The RF signal is modulated with digital information that is converted by an interface in the home or small business into Ethernet compatible data.

To gain a good understanding of how PLC Works an excellent understanding of the Power Grid is required. Unlike telephony and it's ass ....etc

Abstract”

In this work we propose a method to identify the raga of a Carnatic music signal. Raga is analogous to melody in Western music but is much richer and stronger in its representation. The main motive behind Raga identification is that it can be used as a good basis for music information retrieval of Carnatic music songs or Film songs based on Carnatic music. The input polyphonic music signal is analyzed and made to pass through a signal separation algorithm to separate the instrument and the vocal signal. After extracting the ....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. They do a dece ....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

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

An integrated photonic microwave bandpass filter has been demonstrated incorporating a coherently coupled microring resonator in low-loss polymers. The resonator was designed to have an extremely small bandwidth so that it could be used to selectively pass the optical signal carrying the microwave signal to attain efficient bandpass filtering. The demonstrated device may feature compact size, simple structure, stable operation, possible tuning via the thermooptic effect, and furthermore flexible integration with other electrical/opt ....etc
