摘要

随着智能电网的发展，电力线通信(PLC)变得越来越重要。与传统调制相比，正交频分复用(OFDM)具有充分利用频谱、固有的对窄带干扰的鲁棒性以及在多径环境下的出色鲁棒性等优点。本文对基于fft的OFDM在宽带-PLC (BB-PLC)和窄带-PLC (NB-PLC)中的应用进行了比较，通过实验得到了PLC的信道特性，并对正在制定的标准提出了一些建议。

FFT-Based OFDM in Broadband-PLC and Narrowband-PLC

With the development of the smart grid, power line communications (PLC) is becoming more and more important. Compared with traditional modulation, Orthogonal Frequency Division Multiplexing (OFDM) has the advantages of the full use of spectrum, inherent robustness against narrowband interference, and excellent robustness in multi-path environments. This article is devoted to compare FFT-based OFDM in Broadband-PLC (BB-PLC) with in Narrowband-PLC (NB-PLC), conduct experiments to get the PLC channel characteristics and give some advice to the standard in progress.
