Abstract
Interferences to ISDB-T terrestrial digital TV receptions at home and relay stations by a distant terrestrial digital TV airwave are caused by anomalous radio propagations such as radio ducting. It is often extremely difficult to search the interfering station because the interfering airwave is commonly unstable and easily masked by a desired digital TV airwave. To conduct efficient search of the interfering station, an ISDB-T receiver with a network ID estimation function and an ISDB-T interfering airwave extractor have been developed. In this paper, these equipments are introduced and some results of the performance confirmation tests are also reported.
