Power line communication ( plc ) is a communication mode using the power line 電力線通訊( powerlinecommunication )簡(jiǎn)稱plc ,是利用現(xiàn)有電力傳輸線作為傳輸媒介的一種通訊方式。
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 介紹了電力線通信( plc )及電力線信道特性,提出了基于ofdm的實(shí)現(xiàn)方案,并對(duì)ofdm信道進(jìn)行了估計(jì),對(duì)電力線上的ofdm信噪比進(jìn)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 電力線通信是繼電信、電話、無(wú)線通訊、衛(wèi)星通訊之后的又一通信網(wǎng)。電力線載波通訊就是以電力網(wǎng)作為信道,實(shí)現(xiàn)數(shù)據(jù)傳遞和信息交換。
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,近年來(lái)通信和調(diào)制技術(shù)的發(fā)展,特別是自適應(yīng)數(shù)字信號(hào)處理和錯(cuò)誤檢測(cè)及糾正技術(shù),使電力線通信技術(shù)出現(xiàn)新的mac層和物理層協(xié)議,其性能可以和一些專(zhuān)用有線網(wǎng)絡(luò)以及最近十年流行的無(wú)線局域網(wǎng)技術(shù)想媲美。在2001年,一個(gè)由13個(gè)公司(包括cisco , motorola , intel , panasonic , andtexasinstruments )組成的組成的標(biāo)準(zhǔn)組織? ? homeplugpowerline聯(lián)盟,頒布了完整的homeplug1 . 0規(guī)范,改規(guī)范使基于正交頻分復(fù)用技術(shù),主要針對(duì)10mb s室內(nèi)電力線網(wǎng)絡(luò)技術(shù)。
