whitepaper Data centers are at the core of business activity, and the growing transmission speed and density of active data center equipment is placing ever-increasing demands on the physical layer. Enterprises are experiencing enormous growth rates in the...
[11 May 2008]
whitepaper That's why a data-centric approach is called for - one that examines all transmission of information for critical patterns, without compromising database, application, or network performance. Data breaches are becoming a high-profile element of the...

whitepaper ConGES wanted to guarantee rapid, automatic, bidirectional rules-based data synchronization between field engineers and back-office staff and eliminate risk of transmission failure or communication delays.
[11 May 2008]
News Galileo project manager, Javier Benedicto, said the successful signal transmission is a true representation of the advanced satellite positioning services Galileo will be able to offer. A test satellite for the European Galileo programme, Giove-B...

whitepaper In the evaluation it considers MIMO-OFDM transmission. This paper investigates the capacity of Compress-and-Forward (C&F) cooperative relaying scheme when the C&F relay operates in Time Division Duplex (TDD).
[11 Apr 2008]
whitepaper One is optimal antenna selection in the reception phase and the other is signal transmission over each OFDM subchannel. This paper proposes a new diversity technique for broadband wireless access systems that uses orthogonal frequency division...
[10 Apr 2008]
whitepaper This paper examines the performance of a specific MD video coder on a specific real system, namely the Enhanced General Packet Radio Services (EGPRS) cellular network. For an accurate basis of comparison, it examines the performance of one and two...

whitepaper The Sparkasse savings bank in Rugen has opted for a thin-client solution for its regional network in order to make optimal use of its existing 64KB data lines for planned expansions. To avoid the constant retransmission of graphic image content...
[10 Apr 2008]
whitepaper Multiple transmit and receive antennas can be used with orthogonal frequency division multiplexing to improve performance and transmission rate. The basic model of OFDM-based spatial multiplexer is very suitable for high data rate transmission, and...
[10 Apr 2008]
whitepaper This white paper discusses about Asynchronous Transfer Mode (ATM) technology which is a standard for the transmission of information. Its ability to accommodate the simultaneous transmission of data, voice, and video is supporting real-time voice...
[10 Apr 2008]
whitepaper Orthogonal frequency division multiplexing (OFDM) is a special case of multicarrier transmission, where a single datastream is transmitted over a number of lower rate subcarriers. This new standard is the first one to use OFDM in packet-based...
[10 Apr 2008]
whitepaper This paper defines information theoretic problems in the cooperative detection of targets by a distributed wireless sensor network, and in the cooperative transmission of the results to a remote user.
[10 Apr 2008]
whitepaper Link Adaptation (LA) is a powerful means of increasing throughput in wireless channels by customizing the transmission rate based on channel state information (CSI) at the transmitter. This paper considers link adaptation in an orthogonal frequency...
[10 Apr 2008]
whitepaper This paper compares two block transmission systems over frequency-selective fading channels: orthogonal frequency-division multiplexing (OFDM) versus single-carrier modulated blocks with zero padding (ZP).
[10 Apr 2008]
whitepaper Today's information economy depends on the transmission of data, voice and multimedia across telecommunication networks. Despite new technologies that enable legacy copper telephone lines to carry information more efficiently, optical networks...
[10 Apr 2008]
whitepaper In general terms, RFID is a means of identifying a person or object using a radio frequency transmission. In basic terms, an RFID transponder will identify itself when it detects a signal from a compatible device, known as a reader or interrogator...
[10 Apr 2008]
whitepaper Microsoft Windows NT version 4.0 includes features and components for Transmission Control Protocol/Internet Protocol (TCP/IP)-based connectivity. TCP/IP is used on the worldwide Internet and is also widely deployed in private networks ranging from...
[10 Apr 2008]
whitepaper Digital television (DTV) is the transmission of television signals using digital signals rather than conventional analog methods. This white paper gives an overview of Multimedia Home Platform and the underlying technologies and standards.
[10 Apr 2008]
whitepaper The effects of non-ideal transmission conditions of the OFDM system including channel estimation errors, symbol timing offset, carrier and sampling clock offset, phase noise and time-selective fading are analyzed.
