摘　　要：分析了基于DVB-T标准的数字电视接收机现有的成熟方案,针对移动数字电视接收系统的特点提出一种基于DSP+ FPGA结构的前端硬件平台设计方案,并给出了硬件实现总体框图和部分软件实现。采用这种设计方案,能有效抗多径干扰和衰落,满足系统灵活性和实时性的需要。This paper analyzes the scheme of the Digital TV receiver based on the DVB-T standard, and proposes a design scheme of the front-end hardware platform based on the DSP and FPGA structure. The system block diagram of the hardware and partial software are introduced. The design scheme is effective in resisting against muhipath fading and interference, meeting the need of the system to flexibility and real-time operating.
