Field Trial Results for ATSC 3.0 TxID Transmission and Detection in Single Frequency Network of Seoul

In this paper, we provide and analyze the first ATSC 3.0 transmitter identification (TxID) based field test results in the single frequency network (SFN) environment of the Seoul metropolitan area, particularly where four transmitters are operating. For the field trial, a 900 W transmitter with an ATSC 3.0 TxID transmission function was developed and installed in the SFN environment. Moreover, a hardware receiver capable of TxID signal detection was also developed. It is confirmed that TxID signal detection is possible under the SFN channel condition. It is expected that our results will help the broadcasters optimize the ATSC 3.0 SFN coverage.
