Implementation of Transmitter Identification Signal Analyzer in Single Frequency Network

This paper presents the transmitter identification (TxID) signal analyzer for the ATSC terrestrial digital TV system in single frequency networks (SFNs). The structure of the TxID signal analyzer and its practical use in SFN environment are presented with a theoretical approach of the performance measurement The proposed TxID signal analyzer shows robustness at low carrier to noise ratio (CNR), and improvement of analyzing performance using ensemble averaging scheme. The laboratory test results are provided to evaluate the performance of TxID signal analyzer.
