摘要
在概述低压电力线通信技术主要研究方向的基础上,总结了输入阻抗特性、信号衰减特性、噪声特性及信道模型方面的最新研究成果和相应策略。分析了当前热点研究的低压电力线通信调制解调技术(正交频分复用技术OFDM)。通信组网技术则研究了考虑网络有效性和服务需求的蚁群优化路由算法。最后,对低压电力线通信技术的未来研究方向和发展潜力进行了展望。
Based on the introduction of current major research directions of low voltage power line communication technology, this paper summarized the latest research achievements and corresponding schemes, including impedance characteristics, noise characteristic, attenuation characteristic of signal and channel models. Also, the paper analyzed the modulation-demodulation technology of low voltage power line communication （ orthogonal frequency division multiplexing technology ） , which is regarded as the research highlight at present. And then, some research was done on the ant colony optimization routing algorithm which considers network availability and service requirements of power line carrier communication networks. Finally, the future research direction and development potential of low voltage power line communication technology were prospected.
