摘　　要：本文介绍了正交多载波调制(OFDM)电力线通信(PLC)的优缺点,强调了电力线信道存在的噪声和衰减。着重分析了正交多载波调制(OFDM)技术的原理及在电力线信道下的误码性能。最后,讨论了电力线通信技术的应用情况和发展前景。This article mainly introduces the orthogonal frequency division multiplexing(OFDM) of the power line communications(PLC) and its advantages and disadvantages,emphasizing that the power line channel weakens and noise exists.The orthogonal frequency division multiplexing(OFDM) is outlined and the error rate is analysed.Finally,the power line communication application situation in the domestic and the prospects for development are discussed.
