摘　　要：随着多媒体应用以及Ｉｎｔｅｒｎｅｔ的迅速普及，人们对在公共交换电话网（ＧＳＴＮ）上传输数据的Ｍｏｄｅｍ的速度要求越来越高。基于此，本文对高速Ｍｏｄｅｍ的两个关键技术－定时与载波的恢复进行了讨论。提出了一种有效的同步方案，并给出了有关的仿真结果。With the rapid popularization of multimedia applications and the Internet, the data rates of the Modems on GSTN are required to be more and more high. Based on this background, two key techniques of high - speed Modems, timing and carrier phase recovery, are discussed in this paper, An effective synchronization scheme with corresponding simulation results are presented also.
