【摘要】Many advantages of power carrier communication have been studied by a large number of scholars, and the interference can reduce the reliability and efifciency of data transmission. From the perspective of modulation technology, this paper analyzes the existing measures to suppress interference to reduce the impact of interference on power line communication, such as spread spectrum technology, OFDM and so on. Finally, the modulation technology which was best one must be determined according to the characteristics of PLC network media.%电力载波通信的众多优点得到了大量学者的研究，同时，产生的干扰也降低了数据传输的可靠性和高效性。从调制技术角度而言，文章分析了现有的几种抑制干扰措施，扩频技术，OFDM技术等，以减小干扰对电力线通信的影响。最后提出了调制技术必须根据PLC网络介质的特性来确定。
