The SFN-GF system design technology : Experiment of the SFN-GF service area that synthesized antennas directivity

Abstract

It is researched to establish of the SFN-GF technology for poor reception of the digital terrestrial television broadcasting. We study of a design for the relay station used to improve the poor reception that occurs in urban areas. And, the formation method to cover target area from the near place to the far place efficiently is to combination some antennas. We discuss about the result of experiment of combined antennas.
