摘要
本文通过对宽带数据链及其关键技术的研究,提出了一种基于DSP的数字调幅广播DRM(DigitalRadioMondiale)编码调制器的实现方案,给出了编码调制器的功能结构描述、硬件实现方案和软件流程,并针对DRM标准中没有涉及到,但同时是OFDM系统中普遍具有的两个问题——带外抑制和峰均比,都给出了基于DSP的具体解决方法。
Through the researches of broadband data link systems and key technologies, a realization scheme of DRM （Digital Radio Mondiale） coding and modulation on single DSP chip is proposed in the paper, The function structure, the hardware architecture, and software flow chart are represented in the paper. We also give the resolution scheme of two common problems with OFDM system, which are not involved in the ETSI DRM standard, out-of-band rejection and peak-to-average power ratio.
