The emergence of the rapid and phenomenal growth of wireless communication services has created an ever increasing demand for the frequency resource. The radio frequency spectrum is a scare resource and to meet the growing demands of all these bandwidth hungry services, efficient utilization of such radio frequency is essential. Single frequency network (SFN) has emerged as a promising solution for the efficient use of spectrum in terrestrial broadcasting. The Advanced Television Systems Committee (ATSC) 3.0 physical layer standard has adopted transmitter identification (TxID) technology which allows to measure the individual and/or whole network channel response in SFN environments, making it easier for broadcasters to manage and monitor the network. Since TxID is embedded into the host ATSC 3.0 frame as radio frequency watermark, it is transparent to legacy ATSC 3.0 receivers and only a specially designed TxID analyzer is able to detect and analyze it. The first generation digital terrestrial broadcasting system, ATSC 1.0, was designed based on single carrier transmission. On the other hand, the second generation digital terrestrial broadcasting system, ATSC 3.0, was designed on the basis of orthogonal frequency division multiplexing. Due to the differences in transmission techniques for each generation, the detection performance of the transmitter identification signal is also affected. Consequently, only the transmitter identification signal analyzer structure for the existing first generation digital terrestrial broadcasting system can not provide sufficient detection performance in the second generation digital terrestrial broadcasting system. The goal of this dissertation is to investigate theoretical detection performance of ATSC 3.0 TxID and develop practical detection schemes for ATSC 3.0 TxID analyzer. In Chapter 1, we generally introduce the background of ATSC 3.0 TxID technique and describe the overview of contributions. Next, in Chapter 2, we explain the basic procedure of ATSC 3.0 TxID signal generation, the ATSC 3.0 frame structure, and its related problems such as the limited detection performance that occurs when the conventional detection scheme designed for first-generation digital terrestrial broadcast systems is applied directly to ATSC 3.0 system. In order to overcome such problems, three detection schemes are proposed in consideration of implementation complexity and detection performance. In addition, we also derive the theoretical detection performance of ATSC 3.0 TxID signal in SFN environments. In Chapter 3, the test results including computer simulation, laboratory test, and field test are provided. Through the test results, it is proven that the proposed scheme can offer a significant performance gain compared to the conventional scheme. Thus, we believe that this dissertation enables to provide the guideline of better ATSC 3.0 TxID analyzer design. In Chapter 4, serveral use cases for ATSC 3.0 TxID applications are presented. For location estimation, we study the performance bound on the TxID-based location finding in consideration of the proposed scheme.
