- Advanced Systems Television Committee (ATSC) 3.0, the recently developed next-generation digital terrestrial television (DTT) standard, supports an enhanced single frequency network (SFN) for efficient spectrum usage. For constructing a nationwide SFN, transmitter identification (TxID) is a key technology that enables controlling transmitters and analyzing propagation channels between individual transmitters and a receiver. However, since the TxID signal is superimposed on the first preamble symbol of the host ATSC signal, the preamble may be contaminated depending on the injection level of the TxID signal. This paper describes the effects of the TxID signal on the preamble symbol according to the injection levels and protection modes from theoretical and practical perspectives.
