摘要
针对欧洲电信联盟(ETSI)最新提出的模拟广播数字化标准DRM+,介绍了一种接收DRM+数字广播的软件接收机方案,并详细叙述了软件接收机的关键技术环节。该接收机的硬件工作平台以DM3730处理器为核心,采用DSPLink技术,实现DRM+广播信号的实时接收;接收机系统平台为Windows Embedded CE 6.0,采用OFDM信号同步技术,实现DRM+广播信号业务的正确输出。经过测试,该设计能够实时准确地获取DRM+广播信号所提供的音频、文本和图像等业务信息。
DRM＋ is the latest standard proposed by ETSI to digitalize the conventional analog broadcast.A solution for receiving DRM＋ digital broadcast is introduced and some key parts of the software receiver are described in details.The hardware workspace of the receiver is based on DM3730 processor and DSPLink technique is introduced to achieve the real-time reception of the DRM＋ broadcast;the operating system of the receiver is Windows Embedded CE 6.0,OFDM signal synchronization method is used to get the correct service information of the DRM＋ broadcast.It is proved that this receiver can precisely get the audio,text and image information carried by the DRM＋ broadcast signal.
