본 논문에서는 이동통신의 스트리트 셀 가시선 환경에서 통신 품질의 저하 없이 대규모 MIMO 기지국 안테나의 제한된 공간에 다수의 안테나 요소를 배치하는 알고리즘을 제시한다. 제안하는 알고리즘은 상관계수의 특성에 대한 기초적인 검토를 통해 얻은 결과를 바탕으로 구성된 알고리즘에 따라 기지국 안테나의 두 요소의 채널 응답 간의 상관계수를 목적함수로 하는 수학적 최적화를 이용하여 작동한다. 채널 응답 사이. 채널 응답은 광선 추적을 통해 얻은 전파 경로 정보를 사용하여 계산됩니다. 제안된 알고리즘에 의해 출력된 배열은 주로 단일 사용자 및 다중 사용자 환경에서 수직면의 균일한 간격 배열과 채널 용량 비교를 통해 평가됩니다. 다운링크에서 이러한 배열의 평가 결과는 특히 사용자 수 증가에 대한 견고성 측면에서 제안된 알고리즘에 의해 생성된 배열의 우수성을 입증합니다.

Abstract: This paper presents an algorithm to arrange a large number of antenna elements in the limited space of massive MIMO base station antenna without degrading the communication quality under a street-cell line-of-sight environment in mobile communications. The proposed algorithm works by using mathematical optimization in which the objective function is the correlation coefficient between the channel responses of two elements of the base station antenna, according to an algorithm constructed based on the results obtained through basic examinations of the characteristics of the correlation coefficient between channel responses. The channel responses are computed by using the propagation path information obtained by ray-tracing. The arrangements output by the proposed algorithm are mainly evaluated by channel capacity comparison with uniformly spaced arrangements on the vertical plane in single user and multiuser environments. The evaluation results of these arrangements in downlink demonstrate the superiority of the arrangements generated by the proposed algorithm, especially in term of robustness against an increase in the number of users.
