数字高清晰度电视地面广播COFDM传输方案

COFDm Scheme of Digital HDTV Terrestrial Broadcasting Transmission System

摘要: 数字高清晰度电视是新一代电视的发展方向,常用的传输方案是编玛正交频分复用(COFDM)方案和大联盟(GA)的残留边带调制(VSB)方案。文中介绍了在于COFDM的数字高清晰度电视全数字发送部分的基本传输方案和硬件实现,分析了误码率等性能,并给出了实验结果。

Abstract: The digital HDTV is the new generation of television system which is under researches all over the world. One of the key techniques and major problems in the developing of digital HDTV is that coded orthogonal frequency division multiplexing (COFDM) transmission scheme. This paper proposed a COFDM scheme and its hardware implementation. The results of computer simulation are also discussed.
