“…The modern broadcast systems are likely to be deployed single frequency network (SFN)-based, due to a lack of spectrum resources [1]- [5]. However, SFNs have a potential inter-symbol interference problem since the broadcast signals lagged more than an acceptable delay range (i.e., guard interval or time-domain window size) rather bother the signal decoding [6].…”

This paper investigates the detection error of radio frequency (RF)-watermark type transmitter identification (TxID) signal in a single frequency network (SFN). Based on the Cramer-Rao bound (CRB) of TxID detection, closed-form failure probabilities for TxID detection are derived. In order to reflect the practical network condition, the interference from Poisson-distributed out-of-guard interval transmitters is accounted for TxID detection failure probability (TDFP). The proposed approach consequently examines the possible TDFP gain that can be obtained by applying successive preamble cancellation to the TxID detection. Numerical results reveal that the performance of the preamble cancellation-assisted technique is dependent on the threshold signal-to-interference noise ratio (SINR) for preamble signal detection. Nevertheless, the assistance of preamble cancellation is verified to guarantee more than 4 dB improvement of TxID detection capability under practical preamble signal configurations. INDEX TERMS Transmitter identification (TxID), successive interference cancellation (SIC), Poisson point process (PPP).

<p>Local content insertion enabled single frequency networks (SFN) for TV broadcast is a topic of considerable research interest. The SFN broadcast system is not ideally suited for localized content, but it offers enormous spatial diversity and power gain advantages. Orthogonal Frequency Division Multiple Access (OFDMA) allows reserving a fraction of available subcarriers for broadcasting local content. However, a user in the transition region from one local service area (LSA) to another experiences high co-channel interference (CCI). This work explores the possibility of using a `buffer zone' based on universal frequency reuse schemes. In such systems, the power allocation to each content is varied to reduce the CCI-dominated region in the LSA boundary. Simulation results show that depending on the threshold signal-to-interference plus noise (SINR) ratio selected, the proposed buffer architectures increase the percentage of users served by the SFN compared to the scheme where such a buffer is absent. Moreover, the proposed method is spectrally efficient compared to an orthogonal allocation of local content across the LSAs.</p>

“…By contrast, the ATSC 3.0 broadcasters recently posed difficulty in constructing large-scale networks. One of the major features of ATSC 3.0 is a single-frequency network (SFN)-friendly design that allows broadcasters to cope well with spectrum scarcity and band regulations [18][19][20][21][22][23]. Thanks to this SFN capability, it became able to build a nationwide network within a single radio band.…”

Despite the successful launch of Advanced Television Systems Committee (ATSC) 3.0 broadcasting worldwide, broadcasters are facing obstacles in constructing void-less large-scale single-frequency networks (SFNs). The bottleneck is the absence of decent on-channel repeater (OCR) solutions necessary for SFNs. In the real world, OCRs suffer from the maleficent feedback interference (FI) problem, which overwhelms the desired input signal. Moreover, the undesired multipaths between studio-linked transmitters and the OCR deteriorate the forward signals' quality as well. These problems crucially restrict the feasibility of conventional OCR systems, arousing the strong need for cost-worthy advanced OCR solutions. This paper presents an ATSC 3.0-specific solution of advanced OCR that solves the FI problem and refines the input signal. To this end, the FI canceler and channel equalizer functionalities are carefully implemented into the OCR system. The presented OCR system is designed to be fully compliant with the ATSC 3.0 specifications and performs a fast and efficient signal processing by exploiting the specific frame structure. The real product of ATSC 3.0 OCR is fabricated as well, and its feasibility is verified via field and laboratory experiments. The implemented solution is installed at a commercial on-air site and shown to provide substantial coverage gain in practice.
