Studies on Optical Vestigial Sideband Modulation Formats and Key Techniques of OTDM System 光残余边带调制码型与光时分复用系统关键技术的研究
Multilevel vestigial sideband modulation ( VSB ) in HDTV can be implemented by analog or digital method. 高清晰度电视(HDTV)中的多电平残留边带(VSB)调制(VSB)既可用模拟的方法也可用数字的方法实现。
Vestigial Sideband modulation ( VSB ) is used in traditional TV broadcasting. 残留边带(VSB)调制(VSB)已用于现行电视的广播传输中。
In this paper, structure and algorithm of the equalizer used in cable standard of HDTV VSB ( Vestigial Sideband ) system and DVB ( Digital Video Broadcasting ) system are analyzed, and similarities and differences are given in algorithm and ASIC implementation in VSB system is given. 本文探讨了HDTV地面残留边带(VSB)调制(VSB)系统和DVB系统的电缆标准中均衡器的结构与算法,讨论了他们的异同点以及给出了芯片实现方案。
One format combines the vestigial sideband payload and wavelength label. 一种是利用残留边带(VSB)载荷及单边带副载波标签或波长标签的方案。
