- A Single frequency network (SFN) design based on the Advanced Television Systems Committee (ATSC) terrestrial digital television (DTV) system normally causes interference among signals from multiple transmitters or repeaters in the network. The ATSC recommended practice (RP) A/111 introduces transmitter identification (TxID) signals embedded to the ATSC 8-VSB signals. A TxID signal analyzer is then used to detect the TxID signals and analyze the network. Following the analysis results, the SFN design can be managed by adjusting delay and power of multiple transmitters and repeaters. This paper presents basic concept of the Kasami sequence used as the TxID signals, and their insertion method to the ATSC 8-VSB signals. The structure of the TxID signal analyzer to efficiently detect TxID signals is proposed, and a theoretical approach to performance measurement of the TxID signal analyzer is discussed. In addition, computer simulation and laboratory test results are provided to evaluate the performance of the TxID signal analyzer. © 2008 IEEE.
