利用4电平残留边带健壮数据发送和接收对偶流的数字电视发送器和接收器
Abstract:
本发明涉及遵从美国高级电视系统委员会(ATSC)的数字电视(DTV)标准(A/53)的残留边带(VSB)数字电视及其方法。更具体地说，本发明提供了与正常和健壮数据的混合比无关，无需提高平均功率，通过发送和接收由正常数据和健壮数据形成的对偶流就可以改善接收器的接收性能的4-VSBDTV收发器。本发明的4-VSB DTV收发器包括编码健壮数据的编码单元，将健壮数据映射到具有四个电平的两个组{-5，-3，1，7}和{-7，-1，3，5}之一。
Abstract(English):

The present invention relates to a Vestigial Side Band (VSB) Digital Television (DTV) in agreement with the DTV standards (A/53) of the Advanced Television System Committee (ATSC), and to a method thereof. More particularly, it provides 4-VSB DTV transceiver that improves reception performance of a receiver by transmitting and receiving dual streams formed of normal data and robust data without increasing average power, regardless of a mixing ratio of the normal and robust data. The 4-VSB DTV transceiver of the present research includes an encoding unit for encoding the robust data to be mapped to one of two groups having 4 levels {-5, -3, 1, 7} and {-7, -1, 3, 5}.
