OFDM Synchronous Detection Method Based on Mitchell Algorithm for Power Line Communication
To improve the accuracy of OFDM timing synchronization in power line communication system,based on the physical layer communication protocol under the technical specification of low-voltage power line broadband carrier communication interconnection,this paper proposes a power line carrier communication symbol timing algorithm based on Mitchell algorithm.Compared with the theoretical local cross-correlation synchronization algorithm,the proposed algorithm does not require multiplication and is easy to implement in hardware.Compared with the simplified single-bit quantization algorithm,the proposed algorithm has more accurate synchronization detection results,smaller peak sidelobe and more accurate symbol timing under low SNR conditions.
