초록

본 논문은 781MHz 대역에서 안테나 상관도를 고려한 MIMO 채널 측정을 통해, 측정 데이터를 분석하고 채널 특성을 도출하였다. 상기 주파수 대역은 DTV 시스템에서 이동통신 주파수로 할당이 예정된 대역이다. 781MHz 주파수 대역은 900MHz 이동통신 시스템의 채널특성이 일정부분 유사하지만, 상당히 다른 부분이 있음을 기존 연구를 통해 증명하였다. 또한, 안테나의 상관도를 고려할 경우 신호전달 과정에 대한 보다 정확한 예측을 위해서는 채널 특성 연구가 필요하다. 기존 DTV 방송과 혼신을 피하기 위하여 측정은 제주도 인근 도심지역에서 채널사운더와 $4{\times}4$ 안테나로 채널특성을 측정하였다. 측정된 데이터를 바탕으로 도심지역에서 안테나 상관도를 고려한 채널특성을 도출하였다.

In this paper, the measurement data is analyzed and channel characteristics are derived through MIMO Channel measurements at 781MHz considering antenna correlation. 781MHz frequency band currently operates the DTV system, however, it will be allocated new mobile communication frequency band. The channel characteristics at 781MHz seem to be similar existing mobile communication system at 900MHz but quite a different part of the existing research has demonstrated. In addition, the signal procedure of the channel characteristics, considering the correlation of the antenna, for a more accurate prediction research is needed. To avoid interference with Korean DTV broadcasting, we measured channel characteristics in urban areas of Jeju island by channel sounder and $4{\times}4$ antenna. Channel characteristics with antenna correlation were derived based on the measured data in the urban area.
