본 논문에서는 에뮬레이트된 다중 경로 전파 환경에서 인체 효과를 포함하여 핸드셋 안테나가 수신한 신호 간의 공간 상관 특성을 평가할 수 있는 Clarke 모델을 기반으로 하는 공간 페이딩 에뮬레이터에 대해 설명합니다. 제안된 모델은 산란기, 위상 천이기, 감쇠기로 구성됩니다. 산란체는 원의 둘레에 동일한 간격으로 위치합니다. 제어 회로의 위상 천이기 및 감쇠기는 중앙에서 생성되는 Rayleigh 또는 Nakagami-Rice 분포와 같은 다중 경로 전파 환경을 에뮬레이트하기 위해 산란기에서 방사되는 각 파동의 위상 및 진폭을 제어하는 데 사용됩니다. 본 논문에서는 안테나 간 공간 상관 특성을 평가하는 데 사용할 수 있는 수신 안테나 간 최대 거리를 실험적으로 조사하였다. 측정 결과, 병렬 다이폴 안테나를 수신 안테나로 사용한 경우 15 λ의 분기 분리 내에서 공간 상관 특성을 평가하는 데 반경 1.5 m의 산란기 1.7개면 충분함을 보여줍니다.

Abstract: This paper describes a spatial fading emulator based on Clarke's model that can evaluate spatial correlation characteristics between signals received by handset antennas including human-body effect under emulated multipath propagation environments. The proposed model is composed of scatterers, phase-shifters and attenuators. The scatterers are located at equal intervals on the circumference of a circle. Phase shifters and attenuators in a control circuit are used to control the phase and amplitude of each wave radiated from the scatterers in order to emulate multi-path propagation environments, such as Rayleigh or Nakagami-Rice distribution, to be generated at their center. In this paper, the maximum distance between receiving antennas that could be used to evaluate spatial correlation characteristics between antennas was investigated experimentally. The measurement results show that 15 scatterers with a radius of 1.5 m are sufficient to evaluate spatial correlation characteristics within the branch separation of 1.7 λ when parallel dipole antennas are used as receiving antennas.
