ABSTRACT Terrestrial digital (DTV) broadcasting is now underway in the
major markets in the United States after the Federal Communications
Commission (FCC) in several Reports and Orders set the standard on
December 24, 1996, and subsequently released rules of operation and
broadcaster channel allocations. Broadcasters are concerned with many
in-band and out-of-band transmission parameters, including data signal
quality, clock tolerance, radiated power tolerance, carrier phase noise,
adjacent channel emissions, and precision frequency offset requirements.
The FCC permits DTV power-level changes and/or transmitting antenna
location and height and beam tilt in the context of the minimum
interference levels. The Advanced Television Systems Committee (ATSC)
has provided guidelines for broadcasters in the form of suggested
compliance specifications, which are covered in this paper

    ABSTRACT: This paper compares the performances of the ATSC 8-VSB, the DVB-T COFDM, and the ISDB-T BST-OFDM digital television terrestrial transmission systems under different impairments and operating conditions. First, a general system level description is presented. It is followed by comparisons based on laboratory test results and theoretical analyzes. The differences in the system threshold definitions are discussed. In addition, a performance and implementation analysis is also presented for the three transmission systems under different network infrastructures, whenever possible, the impact on the broadcasters or consumers is discussed. Possible performance improvements are also identified

    ABSTRACT: Terrestrial digital television (DTV) requires careful planning in the allocation of RF channels, especially during the transition period when intermixing both analog and digital signals in the same coverage area. One important issue to consider is adjacent channel interference, which limits the number of RF channels utilized in any given area. This issue is important in the deployment of not only full service stations, but also of secondary stations such as translators, on-channel repeaters, and low power television stations. Full service stations have FCC rules that limit the amount of adjacent channel splatter by requiring the splatter energy to remain below a rigid emission mask. Currently there are no FCC rules for translators and low power television stations. The paper discusses typical DTV transmitter splatter sidebands and their causes, as well as specific methods for interference analysis from adjacent channel DTV splatter into adjacent NTSC or DTV signals. Two rigid emission masks ("simple" and "stringent") are proposed and evaluated. Several filter designs are computer simulated and analyzed for minimizing adjacent channel splatter interference as well as in-band DTV signal degradation. Linear pre-correction techniques are analyzed for various length (15-tap and 31-tap) transversal filter equalizers. The simulation is verified by measuring and evaluating DTV system performance for two hardware band-pass filters individually placed at the output of a low power (30 W average) transmitter.

    ABSTRACT: The developmental aspects and technical characteristics of the ATSC RF transmission standard ("8-VSB") are presented. An exposition is given of the planning and allocation methods that were developed, which are generally applicable to the introduction of a simulcast DTV service independent of the type of modulation used. Additional modulation enhancements (E-VSB)are explained. Techniques for implementation of distributed networks of on-channel transmitters are introduced along with references to some specific applications of these techniques.
