电力线载波调制解调器设计
摘要:电力线网络的特点是它覆盖的范围非常广,各种建筑物内都有接入。与常见的 Internet不同,电力线通信(Power-line communication)由于通信线路的特点,是一种近距离的通信方式,它适合“最后一英里”(last mile)的通信接入。而调制解调技术决定了电力线通信的传输速率、传输距离和抗干扰能力,它是电力线通信实现的关键。
本次设计主要涉及电力线载波调制解调器的相关内容,本文通过对电力线信道的初步分析,提出了适合电力线通信的具体实现方案。文章详细介绍了基于FSK调制方式的电力线载波调制解调器的硬件设计,设计内容包括电力线耦合接口的设计、调制解调器的设计和控制器的相关设计等。
通过分析和调试,设计实现了电力线调制解调器(Modem)的相关功能,各项技术指标也达到最初设计任务要求。

The Design of Power Line Carrier Modulator and Demodulator
Abstract: The greatest advantage of the power-line network is that it covers a very wide range. Various buildings have power lines access. Different from the common Internet,because of its communication character, the PLC (Power-line communication)is a short-distance correspondence, it suits to the “last mile” communications access. The technology of modulation and demodulation have an effect on the PLC’s transmission speeds, transmission distance and anti-jamming capabilities, The technique is the key to realize Power-line communication.
The design mainly concerns on the content of power line carrier modulator and demodulator, the paper through primarily analyzing the power line channel, puts forward the specific implement proposal which suits to the power-line communication. The article introduces the hardware design of power line carrier modulator and demodulator in detail which is based on FSK modulator mode, the design content including the design of  power-line coupling interface ,modem and the controller. 
     Through analyzing and debugging, the design realizes the related function of power-line Modem, Various technical indicators have reached the initial design tasks .
 
Keywords: Power-line communication(PLC),Frequency Shift Keying (FSK),Modulation,Demodulation,  Modem
