摘要:

电力线除了向用电设备提供电能外,也可以作为传输信息的通信系统。可靠、高效地传输信息是任何一种通信网络的基本要求,对电力载波通信信道动态负载效应的阻抗特性、多径效应的衰减特性、脉冲噪声的干扰特性等问题进行了分析研究,并从物理层的信号处理以及数据链路层的数据传输角度,分析了几种典型的抑制电力载波通信干扰技术的可行性,进而为探寻有效的抑制电力载波通信脉冲干扰的技术提供了有益的参考。

Abstract:

Power line can provide electrical energy to the electric equipment,and it can also be used as a communications system for transmitting information. The reliable and efficient information transmission is the basic requirement of any kind of communication network. Based on the research of dynamic load impedance characteristic effects,attenuation characteristics of multipath effect and impulse noise interference characteristics,the feasibility of several typical inhibition technologies were analyzed,from perspective of the physical layer signal processing and the data link layer data transmission,which provided valuable reference for exploring effective technologies of pulse interference suppression in the power line communication.

Key words: power line communication, impulse interference, OFDM, IDMA, fractional lower order statistics signal
