摘要
In order to improve the reliability of PLC(Power Line Communication) in harsh environment, a new OFDM(Orthogonal Frequency Division Multiplexing) timing synchronization algorithm is proposed. The proposed algorithm realizes the timing synchronization by improving the calculation process of the timing function in Schmidl and Park algorithms on the basis of the local and correlation method. Simulative results of MATLAB demonstrate that the proposed algorithm achieves higher accuracy of timing synchronization in both AWGN(Additive White Gaussian Noise) channel and PLC channel compared with Park algorithm, and the computational burden of the proposed algorithm is lower. The feasibility of the proposed algorithm is verified by experiments conducted in 220 V AC PLC environment. © 2018, Electric Power Automation Equipment Press. All right reserved.
