Abstract

Antenna arrays at base-stations can be used to transmit and receive information selectively in space by reducing the interference effects. In this paper, a new model of locally scattered signals in the vicinity of mobiles is proposed, and under this model the weights of the beamformer are obtained. Computer simulation results demonstrate that the proposed scheme shows an excellent performance and works well even in the urban environment where there exist many multipath propagations with wide angular spread.

기지국에서 안테나 배열을 쓰면 간섭효과가 줄어들어 공간적으로 선택적인 정보를 보내고 받을 수 있다 이 논문에서는 이동국 근처에서 국소적으로 산란된 신화의 새로운 모형을 제시하고, 이 모형에서 빔형성기의 가중값을 얻는다. 모의실험결과는 제안한 방법의 성능이 매우 뛰어나고, 따라서 각 퍼짐이 넓고 여러길 전파가 심한 도시 환경에 제안한 방법이 알맞음을 보여준다.
