摘要
DRM(Digital Radio Mondiale)是世界上唯一非专利的数字广播系统,它为30MHz以下频段的长波、中波、短波广播提供了数字化的标准。同步算法和信道估计作为其关键技术对系统性能有着十分重要的影响,文章提出了适用于DRM系统的符号同步算法、整数倍载波频偏估计算法、小数倍载波频偏估计算法以及时频域联合信道估计和均衡算法,并对这些算法进行了仿真分析。
DRM（Digital Radio Mondiale） is a global unpatented digital system. It provides a digital system for the short wave,medium wave and long wave broadcasting. Synchronization and channel estimation algorithms as the key technologies of DRM have an important impact on system performance, this paper proposes the symbol synchronization algorithm, Integer and decimal carrier frequency offset estimation and joint time-frequency domain channel estimation algotitbm for DRM system, and these algorithms are detailedly analyzed and simulated in this paper,
