| Abstract: | This paper studies the fundamental principle and implementation of the orthogonal frequency division multi plexing（OFDM） in the lowvohage power line communication. To solve the problem that the peak to average power ratio （PAPR） of the OFDM system is high, an improved phaseinterference method is proposed. The computer simulation verfies the efficiency of the improved method which improves the security and reliability of information transmission. |
