NHK STRL이 개발한 밀리미터파 모바일 카메라(MiMoCam)는 밀리미터파 대역(42GHz/55GHz)을 사용하여 Hi-Vision TV 영상을 고품질과 짧은 지연 시간으로 전송합니다. 송신기와 수신기 모두에서 다수의 안테나를 사용하는 다중 입력 다중 출력(MIMO) 기술을 사용하여 고품질 Hi-Vision TV 영상을 전송하는 데 사용할 수 있습니다. 이 카메라는 다중 경로가 높은 스튜디오 환경에서 사용하도록 의도되었지만 MiMoCam을 야외에서 사용하라는 요청도 많습니다. 이는 반사파가 많지 않은 LOS(가시선) 환경에서 카메라가 작동하는 다양한 채널 통계를 제공합니다. MiMoCam의 실외 환경 사용 가능성을 명확히 하기 위해 제안된 MIMO 시스템의 실외 전송 테스트와 실외 전송 성능을 측정하였다. 본 논문에서는 MiMoCam 시스템의 특징과 MiMoCam에 사용된 MIMO 전송 기술을 소개하고 이번 실외 테스트 결과를 제시한다. 또한, 직교 편파를 이용하여 MIMO 전파 채널의 채널 상관관계를 억제하고, 평균 수신 CNR(Carrier-to-Noise Ratio)에 대한 BER(Bit Error Rate) 특성이 개선되는 것을 확인하였다. 마지막으로, 우리는 이러한 결과로부터 MiMoCam 실외 운용의 타당성을 찾을 수 있었다.

Abstract: The Millimeter-wave Mobile Camera (MiMoCam) developed by NHK STRL uses millimeter-wave band (42 GHz/55 GHz) to transmit Hi-Vision TV picture with high quality and low latency. Multiple-input multiple-output (MIMO) technology which uses a number of antennas at both the transmitter and receiver can be adapted to use to transmit higher quality Hi-Vision TV picture. The camera was intended to be used in a studio environment where there is a high degree of multi-path, however there are also many requests for the MiMoCam to be used outdoor. This will present a different channel statistics where the camera will be operating in a near line-of-sight (LOS) environment without much reflected waves. We have conducted an outdoor transmission test and measured the outdoors transmission performance of the proposed MIMO system to clarify the possibility of using the MiMoCam in outdoor environment. This paper introduces the features of the MiMoCam system and the MIMO transmission technique used in the MiMoCam and presents the findings of this outdoor test. It was also confirmed that channel correlation of the MIMO propagation channels were suppressed by using orthogonally polarized waves and bit error rate (BER) characteristics with respect to the average receiving carrier-to-noise ratio (CNR) was improved. Finally, we could find the feasibility of the MiMoCam outdoor operation from these results.
