본 논문에서는 CCI(동일채널 간섭)를 감소시키는 동시에 원형 셀을 형성할 수 있는 TDMA 시스템용 적응형 어레이를 이용한 상승형 기지국의 새로운 구성을 제안한다. 제안된 기지국은 두 세트의 트랜시버와 안테나 어레이, 그리고 적응형 빔 제어 장치로 구성됩니다. 트랜시버는 서로 다른 시간 슬롯에서 작동합니다. 간섭을 억제하는 원형 셀은 두 안테나 어레이의 패턴 제어를 통합하여 달성됩니다. 제안된 기지국 구성의 효율성은 적응형 배열 테스트베드를 사용한 현장 측정을 통해 평가됩니다. 제안한 기지국은 전방향 안테나를 적용한 기지국에 비해 약 30% 더 큰 채널 용량을 달성하고, 실제 마이크로셀 시스템에서 CCI가 감소된 옴니존을 생성함을 확인한다. 또한, 제안된 기지국은 전방향 안테나를 사용하는 기지국에 비해 약 1.8배 더 넓은 통신 가능 영역을 구축함을 컴퓨터 시뮬레이션을 통해 확인하였다.

Abstract: This paper proposes a novel configuration of an elevated base station using an adaptive array for TDMA systems, which can simultaneously decrease the CCI (co-channel interference) and form a circular cell. The proposed base station comprises two sets of transceivers and antenna arrays, and an adaptive beam control unit. The transceivers work in different time slots. The circular cell that suppresses the interference is achieved by integrating the pattern control of the two antenna arrays. The effectiveness of the proposed base station configuration is evaluated by field measurements using an adaptive array testbed. We confirm that the proposed base station achieves a channel capacity that is approximately 30% greater than that of a base station employing an omni-directional antenna and generates an omni-zone with reduced CCI in an actual microcell system. Furthermore, we confirm by computer simulation that the proposed base station establishes a communicable area that is approximately 1.8 times larger than that of a base station employing an omni-directional antenna.
