对ATSC 3.1版物理层的个人建议

Private Proposals to ATSC 3.1 PHY

ATSC正在积极制定ATSC 3.0版;预计2015年底将完成标准草案。提出其中可补充的3方面技术,作为对ATSC 3.1版物理层的个人建议:1)增加单载波调制的可选项(n-VSB和n-QAM等);2)增加"单频道方案"(仅使用指派频道)实现"回传信道"的可选项,作为"空白频道方案"的补充;3)增加由中国工程师们自主创新的"宽带数字电视(DTV)发射机+M-SFN(多频道单频网)技术"组建DTTB网络,而当它使用于单载波系统的高比特率传输固定接收服务时(如4K/8K-UHDTV),具有一定技术优势。

ATSC 3.0 version is now actively promoted by ATSC, with its schedule of the draft standard completed by the end of 2015. Three possible fields of technology that could be supplemented into ATSC 3.1 PHY are proposed privately in this paper： 1） Single carrier modulations （n-VSB and n-QAM, etc） could be added as options. 2） ＂Single Channel Solution＂ for the return channel could be added as option to ＂White Space Solution＂, using the single assigned channel only. 3） The new technology innovated by Chinese engineers, i.e. the wideband digital television （DTV） emitter ＋ M-SFN （Multiple Channels - Single Frequency Networks） for digital terrestrial television broadcasting （DTTB） networking, could be introduced, as a lot of the advantages of single carrier systems would be realized, especially in the services of high bit-rate fixed reception （i.e., 4K/SK-UHDTV）.
