Abstract:
Interest to allow secondary use on television frequency bands has been growing and recently Federal Communications Commission (FCC) opened vacant TV channels for unlicensed use. Many countries, especially in Europe, are using DVB-T standard for providing terrestrial digital television transmissions, whereas countries like U.S. rely on ATSC standard. When assessing the impact and potential of secondary use, primary system's tolerance to interference must be known. In this paper we provide essential interference tolerance measurement results for DVB-T system that illustrate how secondary use could impact its performance. We show how DVB-T receivers BER behaves under interference and how bursty interference signal affects compared to continuous interference. We also calculate example protection distances for different secondary transmitters.
