Power line communication ( plc ) is a communication mode using the power line 电力线通讯( powerlinecommunication )简称plc ,是利用现有电力传输线作为传输媒介的一种通讯方式。
Power line communication ( plc ) and the characteristic of power line channel are introduced . the scheme based on ofdm is proposed . the performance of the ofdm in power line channel is analyzed 介绍了电力线通信( plc )及电力线信道特性,提出了基于ofdm的实现方案,并对ofdm信道进行了估计,对电力线上的ofdm信噪比进行了分析。
The power line communication ( plc ) is a kind of rising communication mode differing from traiditional communication such as telecommunication , telephone , radio communication , etc . , in that the plc transfers data and exchanges information by means of power line network 电力线通信是继电信、电话、无线通讯、卫星通讯之后的又一通信网。电力线载波通讯就是以电力网作为信道,实现数据传递和信息交换。
On the other hand , recent advances in communication and modulation methodologice , as well as in adaptive digital signal processing and error detection and correction , have opened the way for the development of effective medium access control and physical layer protocols that support power line communications ( plc ) networks operating at speeds comparable to those obtained from specially wired and more recent wireless local area network in mid - 2001 , an industrial standards organization called the homeplug powerline alliance , originally founded by 13 companies including cisco , motorola , intel , panasonic , and texas instruments , announced the completion of the homeplugl . o specification for a l . 0mb / s class in - home power line networking technology based on orthogonal frequency - division multiplexing ( ofdm ) 但是,近年来通信和调制技术的发展,特别是自适应数字信号处理和错误检测及纠正技术,使电力线通信技术出现新的mac层和物理层协议,其性能可以和一些专用有线网络以及最近十年流行的无线局域网技术想媲美。在2001年,一个由13个公司(包括cisco , motorola , intel , panasonic , andtexasinstruments )组成的组成的标准组织? ? homeplugpowerline联盟,颁布了完整的homeplug1 . 0规范,改规范使基于正交频分复用技术,主要针对10mb s室内电力线网络技术。
