| 摘 要： | 残留边带调制（ＶＳＢ）已用于现行电视的广播传输中。由于其在频谱利用率和传输性能方面的优越性，现在美国大联盟方案考虑把它用于高清晰度电视（ＨＤＴＶ）的地面广播。本文介绍应用在全数字ＨＤＴＶ广播传输中的ＶＳＢ原理及其抗多径干扰和ＰＡＬ信号干扰的方法。

| Abstract: | Vestigial Sideband modulation(VSB)is used in traditional TV broadcasting. Becauseof the advantages on spectrum utilization and transmission performance,it is also considered to beused in HDTV terrestrial broadcasting by Grand Alliance(USA).This paper introduces theprinciples of VSB of HDTV digital signal and the methods of combating with multipathinterference and PAL signal interference. |
