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

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 multiplexing(OFDM),the system can realize the function of broadband accessing with high practical applications value.
