基于OFDM的电力载波数据传输模块研究与设计

摘要

In order to transmit data by taking advantage of the already exist power line, the paper proposes a PLC module. The module is designed by OFDM (Orthogonal Frequency Division Multiplexing)LME2980. In the paper, we analyze the characteristic of the power carrier transmission channel and the basic principle of OFDM demodulation technology. Finally, we achieve the design of power carrier data transmission module.%为了实现利用现有的电力线路实现数据传输,提出利用正交频分复用(OFDM)技术芯片LME2980设计电力载波通信(PLC)模块.通过分析电力载波传输信道特性和OFDM调制解调技术基本原理,完成电力载波数据传输模块的设计,实现利用现有的电力线进行数据传输.
