摘　　要：在介绍了基于PC的数字广播(DRM)软件接收机的意义、可行性之后,首先分析了一种DRM软件接收机——Dream的系统结构,建立了DRM信号模型。然后基于信号模型重点研究了Dream软件接收机中的信道估计和同步算法原理,并对其软件设计结构进行了分析。最后通过仿真验证了其具有较好的解调性能。In this paper, after introducing the significance and feasibility of PC-based Digital Radio Mondiale （DRM） receivers, the architecture of Dream software receiver was presented, and its DRM signal model was constructed. Then, based on the signal model, the algorithm theory of channel estimation and synchronization were studied particularly. The software framework of Dream receiver was analyzed. Simulation results show that the receiver is good at demodulating DRM signals.
