  • In this paper, out-of-band emission regulations and measurement methods of terrestrial DTV broadcasting services are analyzed, and a novel method to evaluate the out-of-band emission characteristics of DTV transmitter is proposed. Experimental results show that proposed method can be easily used to measure the characteristics of DTV transmitter with inexpensive measuring equipments. With a few modifications, proposed method can be widely adopted to measure the RF performances of the general radio equipments efficiently.

  • In this paper, worldwide standards and regulations on in-band/out-of-band emission characteristics of DTV broadcasting equipments are reviewed, and emission mask requirements of several equipment types are analyzed. Out-of-band emission mask draft suitable for DTV repeater is proposed and its usefulness is evaluated and verified in the experiments. Using the proposed standard, small-sized and cost effective DTV repeater can be implemented to broaden DTV broadcasting coverage for digital switchover.

  • In this paper, worldwide standards and regulations on in-band/out-of-band emission characteristics of DMB broadcasting equipments are reviewed, and emission mask requirements of terrestrial low power DMB repeater under 10mW/MHz are analyzed. Out-of-band emission mask drafts suitable for single/multiple block low power repeaters are proposed. Validity and usefulness of the proposed drafts is evaluated and verified in the several experiments. Using the proposed standard, small-sized and cost-effective DMB repeater can be easily implemented to broaden DMB broadcasting coverage by reducing weak signal areas.
