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。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接收机的时频域联合信道估计和均衡算法,仿真结果表明上述信道估计算法在DRM接收机中具有较好的性能。
DRM（Digital Radio Mondiale） is a global unpatented digital system.It provides a digital standard for the short wave,medium wave and long wave broadcasting.Channel estimation algorithm as the key technologies of DRM have an important impact on system performance,this paper proposes joint time-frequency domain channel estimation algotithm for DRM receiver.The simulation result shows that the channel estimation algorithms have better performance in DRM receiver.
