摘要

介绍了一种基于OFDMA的低压配电网多址电力线通信调制解调器。基于对法国PLC网络的初步描述，给出了调制解调器的完整描述。它特别关注数据帧结构、子载波分配给用户、用于符号编码的位加载算法、同步和均衡。通过使用简化的噪声模型进行仿真，对所提出的系统进行了评估。

An OFDMA based modem for powerline communications over the low voltage distribution network

The paper describes an OFDMA based modem for multiple access powerline communications (PLC) over the low-voltage distribution network. Relying on a preliminary characterization of the French PLC network, a complete description of the modem is given. It concerns in particular the data frame structure, subcarrier allocation to users, the bit loading algorithm used for symbol coding, synchronization, and equalization. The proposed system is evaluated through simulations carried out using a simplified noise model.
