| Abstract: | In this paper, a power line carrier (PLC) communication system based on a type of coded orthogonal frequency division multiplexing (COFDM) modulation is presented. Some application problems in the COFDM system such as PAPR, synchronization, and channel antiinterference coding are discussed and relevant solving scheme is put forward. The performance of the proposed system with parameters is investigated through computer simulation. A good bit error rate (BER) result is observed. Simulation results show that high data communication could be carried out with the proposed technology in high voltage power line channels. |
