Abstract

OFDM system is very sensitive to synchronization error. Accurate and fast synchronization is the key to the performance of power line carrier communication system based on OFDM. In order to improve the ability of power line carrier communication system to resist harsh channel environment, a local cross-correlation operation method based on compressed binary index is proposed, which greatly reduces the amount of synchronous operation while ensuring the success rate of system communication, the complexity of operation is reduced. MATLAB simulation results show that the synchronization method has strong robustness in a variety of typical noise environments. By optimizing the synchronization sequence, when the communication performance of the system loses about 1dB, the operation efficiency can be improved by more than 50%.
