In past decades we witnessed the rapid development of global communication infrastructure and the explosive growth of the Internet, accompanied by ever-increasing user bandwidth demands and emerging multimedia applications. These dramatic changes in technologies and market demands, combined with government deregulation and fierce competition among data, telcom, and CATV operators, have scramble...

The paper compares different channel models used for modeling Broadband Power-Line Communication (BPLC) system. The models compared are Zimmermann and Dostert, Philipps, Anatory et al and Anatory et al generalized Transmission Line (TL) model. The validity of each model was compared in time domain with ATP-EMTP software which uses transmission line approach. It is found that for a power-line ne...

Broadband power line communication based on an orthogonal frequency division multiplexing scheme is considered in this paper. In addition to multipath fading and frequency selectivity, the power line communication channel is influenced by impulsive noise. More bit errors in power line communications are caused by these effects. In this paper, a relevance vector machine (RVM) is applied to the r...

The main purpose of this paper is to describe and model the characteristics of low voltage distribution lines inside consumer premises, when used as a broadband communication channel. Results from measurements performed both in the laboratory and in residential buildings, are presented and discussed. Also a channel model to simulate the behaviour of these lines for high bit-rate digital communi...

BACKGROUND Domestic and European Union wide directives are encouraging more and more utilities to modernize their distribution grids. Spain became a pioneer by starting to replace traditional metering systems with modern standardized AMR solutions. In addition to the regulatory directives, Iberdrola grabbed this opportunity to think beyond metering. Iberdrola introduced remote management and co...

power-line networks are promise infrastructure for broadband services provision to end users. However, the network performance is affected by stochastic channel changing which is due to load impedances, number of branches and branched line lengths. It has been proposed that multi-carrier modulations techniques such as orthogonal frequency division multiplexing (OFDM), Multi-Carrier Spread Spect...

Power line communication (PLC) has received steady interest over recent decades because of its economic use of existing power lines, and is one of the communication technologies envisaged for Smart Grid (SG) infrastructure. However, power lines are not designed for data communication, and this brings unique challenges for data communication over power lines. In particular for broadband (BB) PLC...
