摘　　要：DRM(Digital Radio Mondiale)是世界上唯一非专利的数字广播系统,它极大地降低了发射功率,提高了频率利用率,减少了发射机的运营成本,使声音的接收质量得到显著改善。同步算法作为其中一种关键技术对系统性能有着十分重要的影响,论文重点分析了DRM接收机同步的各个环节和算法,并对这些同步算法进行了仿真分析。DRM(Digital Radio Mondiale)is a global unpatented digital system.It greatly reduces the transmit power,im-proves the frequency utilization,reduces the transmitter's operation cost,and improves the receiving quality of the sound significant-ly.Synchronization algorithms as one of the key technologies have an important impact on system performance,so every kind of syn-chronization algorithm are detailedly analyzed and simulated in this paper.

关 键 词：DRM 同步算法
