摘要: 随着数据传输技术的发展和各种数据通信网络的广泛应用,对调制解调技术的研究也不断深入。本文介绍一种适用于MAP(制造自动化协议)网络的高性能宽带调制解调器。它采用AM/PSK技术,设计新颖、实现简单,既考虑符合有关国际标准,又考虑满足国内应用需要。该调制解调器具备宽带MAP网络物理层的全部功能,并且在单缆制宽带MAP网络中成功地进行了实验连网。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.
