“…MIMO processing in ATSC 3.0 is only applicable to the data path, and it is not applied to the bootstrap, which is the entry point to the ATSC 3.0 system, and to the preamble with layer-1 (L1) signaling information [19]. The use of MIMO is signaled in the preamble.…”

“…In fact, using bootstrap signals for channel estimation has some drawbacks. The ATSC 3.0 bootstrap signal has a fixed bandwidth of 4.5 MHz, regardless of the actual RF channel bandwidth 6 [53]. For 6-MHz-band configurations, the occupied bandwidth is 5.832844 MHz, which is larger than 4.5 MHz.…”

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.

“…Frame Components Figure 2 shows the high-level components of an ATSC 3.0 physical layer frame which are multiplexed together in time. A bootstrap is located at the beginning of each frame to facilitate the initial acquisition of the frame [3]. Immediately following the bootstrap is a preamble which contains control signaling describing the remainder of the frame, including its contents.…”

An ATSC 3.0 physical layer frame consists of a bootstrap immediately followed by a preamble containing layer 1 control signaling and then one or more subframes carrying payload data. Subframes within a particular frame may be of the same or different types, with different subframe types being configured for different classes of receivers (e.g., mobile versus fixed). This paper focuses on the subframe structure, configuration, and contents, including subframe boundary symbols which carry additional pilots to assist with channel estimation at the receiver and cell multiplexing which maps physical layer pipe (PLP) payload data to physical layer resources within each subframe. Various methods for cell multiplexing multiple PLPs within a subframe are discussed and described, including time division multiplexing, frequency division multiplexing, time-frequency division multiplexing, and layered division multiplexing. Frequency interleaving, pilot insertion, and guard interval insertion are also covered, including a method of distributing extra samples to guard intervals in order to obtain frame lengths equal to an integer number of milliseconds.
