The design for power line carrier communication broadband access network based on OFDM

介绍了一种基于OFDM技术的宽带电力接入网系统设计,该系统适用于低压配电网。OFDM(正交频分复用)技术能克服低压电力线信道的高噪声、多径效应和信道衰落,实现高速数据的传输。以INT5500CS为核心设计出符合HomePlug 1.0-Turbo标准的低压配电网宽带电力接入网系统。整个系统主要分为电力线接口端和以太网接口端。由于采用OFDM通信技术,该系统能实现宽带接入,具有较高的实用价值。

A broadband access network design scheme based on the OFDM is presented, which is adapted to low-voltage power network .OFDM can realize the high-speed data transportation by avoiding the high-noise, multi＇path effect and channel fading. And this paper presents the design of broadband PLC system in low-voltage power network on the basis of INT5500 chipset, which comply with HomePlug 1.0-Turbo standard. The system is mainly composed of two parts： powerline network interface and Ethernet interface. In virtue of orthogonal frequency division muhiplexing（OFDM）, the system can realize the function of broadband accessing with high practical applications value.
