【摘要】 在通信技术高速发展的今天，电力线通信(Power Line Communication)简称为PLC技术，是目前发展前景十分看好的宽带接入技术，利用配电网低压线路传输高速数据、话音、图象等多媒体业务信号的一种通信方式。随着Internet技术的飞速发展，利用220V低压电力线传输高速数据的价值越来越为人们所重视，因为它具有不用布线、覆盖范围广、连接方便的显著特点，被认为是提供宽带网络接入解决方案最具竞争力的技术之一。本文首先介绍了电力线载波通信的概念及应用前景，研究了电力线通信信道的基本特点，建立电力线通信信道的模型，并且基于电力线信道的特点提出一种基于OFDM(正交频分复用)技术的高速电力线载波通信系统。对OFDM技术原理进行了介绍，分析OFDM应用于电力线通信的优点和OFDM中关键技术，建立基于OFDM技术的电力线通信系统的仿真，对系统的性能进行了分析。最后对Intellon公司的电力线通信收发芯片INT5200及以太网控制器KS8721BL的功能和使用进行了说明，在此基础上给出了PLC调制解调器的总体设计方案和各功能模块的具体实现方案。更多还原

【Abstract】 In our ear communication technologe is developing quickly,Power Line Communication (PLC) technology has become the wide band interface techlogy with a bright prospect. It is a communication method make use of low pressure line of the distribution network to transmit high-speed data,voice,image and other mulit-media service signals. With the rapid development of Internet technology,the value of transmitting high-speed data by means of 220V low pressure electricity line has gained people’s attention,for it contains some remarkable features such as no wiring,wide covering and easy connection .It is regarded as one of the most competitive technology of wide band network.This thesis introduces the concept and application prospect of power line communication,makes research on the characteristics of power line channel and power line channel model making,and according to the characteristic of power line channel,puts forward a high-speed power line commumication system based on OFDM(orthogonal frequency division multiplexing) technology.In addition, this thesis introduces the principle of OFDM,analyzes the advantages of applying OFDM to power line communication and the key technology of OFDM,establishes power line commumication system simulation based on OFDM technology and makes performance analysis of the system.Finally,this paper explains the functions and uses of power line communication receiving and dispatching chip INT5200 and Ethernet PHY KS8721BL,and based on the above,put forward the geaeral designing plan of PLC modem and the concrete realization method of individual functioning module.更多还原
