摘　　要：针对电力线通信存在窄带干扰和载波频率偏移对系统传输性能的影响,提出扩展现有的基于OFDM框架下Reed-Solomon卷积码的窄带电力线通信前向纠错方案,即在OFDM的子载波间引入排列码。经过实验表明,该方案不但提高了系统传输得有效性,而且也提高了传输的可靠性。该成果对推进电力线载波通信的应用,具有重要意义。Aiming at the influence of narrowband interference and carrier frequency offset on the transmission performance of power line communication, this paper proposes an extended scheme for forward error correction of narrowband power line communication based on Reed-Solomon convolutional code in OFDM framework, that is, introducing the permutation code between subcarriers of OFDM. Experiments show that the scheme not only improves the efficiency of the system transmission, but also improves the reliability of transmission. The work to promote the application of power line carrier communication, is of great significance.
