A New OFDM Synchronization Scheme for PLC

Hui Wang, Qingsheng Hu, Xiaoyan Wang

Open publisher page 1 citations

Abstract

Aimed at the application of PLC (power line communication), this paper proposed a improved OFDM synchronization scheme on the base of the compare with three ordinary OFDM synchronization algorithms, which are ML algorithm, 802.11a synchronization scheme and the method presented by Schmidl and Cox. Assuring the efficient timing synchronization and the wide frequency estimation, this modified method refines the fractional frequency offset estimation and avoids the estimated distortion at the plusmn1 normalized frequency offset. In addition, the model of the power line has been presented. And based on it, the feasibility of the proposed scheme has been checked by simulation using the matlab/simulink platform.
