Abstract

In this paper, some indoor PLC channel models are compared from an OFDM communication system perspective. Firstly, three representative models have been selected to generate channels in a statistical way, which are later included in an OFDM system simulator designed according to Homeplug-AV parameters. Secondly, the system performance is analyzed for the three cases of channel models and is compared to the one obtained for a set of almost 200 measured channels. An additional study about the Gaussian nature of the linear distortion in the OFDM system caused by the channels (modeled and measured) is presented.

PLC信道模型:基于ofdm的比较
本文从OFDM通信系统的角度比较了几种室内PLC信道模型。首先,选取三个代表性模型进行信道统计生成,然后将其纳入根据Homeplug-AV参数设计的OFDM系统模拟器中。其次,分析了三种信道模型下的系统性能,并与近200个信道模型下的系统性能进行了比较。对OFDM系统中由信道(建模和测量)引起的线性失真的高斯特性进行了进一步的研究。
