This paper introduces three coding strategies for using the Luby Transform (LT) code in a relay aided power-line communication scheme. In the first method, the relay decodes the received packets and re-encodes them for transmission towards the destination. In the second method, the relay only forwardes a random linear combination of its received packets towards the destination, while in the thi...

We present multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) based broadband power line communication (BPLC) using antenna and fading diversity. We evaluate the proposed MIMO-OFDM system over multi-conductor power line channels, with or without cross-talk between the antenna paths. The proposed scheme employs maximum ratio combining (MRC) that effectively com...

This paper represents design broadband impedance matching circuit for Coupler to improve power transfer efficiency in the broadband power line communication (BPLC) systems. The Butterworth gain function equalizer is used to design broadband matching circuit. A practical PLC Coupler impedance matching circuit is designed, and the characteristics for S11 and S21 of PLC Coupler are enhanced compar...

Power-line networks are widely used today for broadband data transmission. However, due to multipaths within the broadband power line communication (BPLC) systems owing to stochastic changes in the network load impedances, branches, etc., network or channel capacity performances are affected. This paper attempts to investigate the performance of typical medium voltage channels that uses Orthogo...

The objective of this paper is to study the feasibility of Broadband technologies for home application in an effective manner and to develop a simplified transfer characteristic model for the low voltage indoor power line for Broadband power line communication based on the transmission line theory using software simulation for generalization purpose as it is already known that there is no such ...

State-of-the-art indoor broadband power line communications (PLC) systems use orthogonal frequency division multiplexing (OFDM) signals with constellations up to 10 bits/symbol, which makes channel estimation a key aspect. This paper focuses on the initial used in payload, might be further adapted by means of decision-directed strategy. estimate has computed per-frame basis and can accomplished...
