摘要: 隨著數(shù)據(jù)傳輸技術(shù)的發(fā)展和各種數(shù)據(jù)通信網(wǎng)絡(luò)的廣泛應(yīng)用,對(duì)調(diào)制解調(diào)技術(shù)的研究也不斷深入。本文介紹一種適用于MAP(制造自動(dòng)化協(xié)議)網(wǎng)絡(luò)的高性能寬帶調(diào)制解調(diào)器。它采用AM/PSK技術(shù),設(shè)計(jì)新穎、實(shí)現(xiàn)簡(jiǎn)單,既考慮符合有關(guān)國(guó)際標(biāo)準(zhǔn),又考慮滿足國(guó)內(nèi)應(yīng)用需要。該調(diào)制解調(diào)器具備寬帶MAP網(wǎng)絡(luò)物理層的全部功能,并且在單纜制寬帶MAP網(wǎng)絡(luò)中成功地進(jìn)行了實(shí)驗(yàn)連網(wǎng)。Abstract: A novel broadband modem wlh high performances suitable for MAP (manufacturing automation protocal) network is introduced It uses the AM/PSK technique. The design isnew and considers not only the related international standards but also the user s requirements.The modem can complete all the physical layer performances of he broadband MAP network and has been used for single-cable broadband MAP networking suvcessfully.
