<p>A method for preventing interference in a T(Terrestrial)-DMB and its system are provided to improve reception performance of a shadow area by preventing poor reception interference positioned between two gap fillers. A gap filler management server transmits radiowaves for power detection to a DMB terminal, and transmits a CQI(Channel Quality Information), including reception power and a terminal ID, to a gap filler corresponding to a gap filler ID of the CQI which has the reception power, the gap filler ID, and the DMB terminal ID received from the DMB terminal(S201-S209). Gap fillers control beam forming of an antenna as checking the reception power of the CQI transmitted according to a pre-set period from the gap filler management server, and increases strength of the antenna beam while increasing beam strength of the relatively weaker side(S211-S213).</p> |
