Laboratory Test Analysis of TxID Impact into ATSC 3.0 Preamble

Advanced Television Systems Committee (ATSC) 3.0 is newly approved standard for a next generation digital television service. In the physical layer standard of ATSC 3.0, the transmitter identification (TxID), which is inserted into a host ATSC 3.0 preamble, is introduced supporting single frequency networks (SFNs). This paper presents impact analysis of TxID signal into the ATSC 3.0 preamble signal according to TxID injection levels. Laboratory tests are intensively performed to analyze possible impact to the host ATSC 3.0 preamble.
