The Research And Application On The Middle Voltage Broadband Power Line Communication On The Basis Of OFDM

In this paper, we introduce history and nowadays of the middle voltage powerline communication. The middle-voltage power line channel characteristics and themodeled are researched. The compose of the system and theory of orthogonalfrequency division multiplexing (OFDM) are discussed and analyzed. The schemeof middle voltage power line on the basis of OFDM is discuss. The emphases of theresearch is the synchronization arithmetic of the OFDM systems of middle voltagepower line. A OFDM system synchronization modeled is proposed and simulateby MATLAB. We have analyzed the arithmetic of synchronization by simulation.The principium of the middle voltage broadband power line digital translationcommunication equipment is analyzed. The framework of the hardware andsoftware of the digital translate communication equipment is established.
