数字电视地面广播接收终端的实现技术

Research on the Realization Technology of Digital Television Terrestrial Broadcasting Receiving Terminal

互联网技术在近些年得到迅猛发展,有效解决了广播电视移动接收问题,然而移动接收电视往往比移动接收广播困难。DMB-TH是移动接收技术标准,其特点在于频谱扩频调制后可彼此重叠,子载波彼此交互,在很大程度上提升了电视频谱利用率。主要分析数字电视地面接收终端的具体实现技术。

Internet technology has been rapidly developed in recent years,which effectively solves the problem of mobile TV reception.However,mobile TV reception is often more difficult than mobile reception broadcasting.DMB-TH is a standard for mobile reception technology,which features that the spectral spread spectrum modulation can overlap with each other and the subcarriers interact with each other,greatly improving the spectrum utilization of the television.The article mainly analyzes the specific technologies for realizing digital terrestrial television receiving terminals.
