摘　　要：详细分析了DRM软件接收机的设计思路和实现方法,介绍了基于PC的软件接收机的工作原理及利用软件构建软件接收机的实现方案,研究了软件接收机的信号解调流程。外场实测结果表明DRM系统性能良好,已具备了推广应用的基础。The design idea and implementation method for software defined receiver of DRM are analyzed. Based on the personal computer software, the implementation scheme of the DRM software defined receiver is introduced, and the signal demodulation flow is also studied. Fileds testing results indicate that the performance is good and the scheme is ready to be promoted and widely applied.
