A câmera móvel de ondas milimétricas (MiMoCam) desenvolvida pela NHK STRL usa banda de ondas milimétricas (42 GHz/55 GHz) para transmitir imagens de TV Hi-Vision com alta qualidade e baixa latência. A tecnologia de múltiplas entradas e saídas múltiplas (MIMO), que usa várias antenas no transmissor e no receptor, pode ser adaptada para transmitir imagens de TV Hi-Vision de maior qualidade. A câmera foi projetada para ser usada em um ambiente de estúdio onde há um alto grau de multipercurso, porém também há muitos pedidos para que a MiMoCam seja usada em ambientes externos. Isso apresentará estatísticas de canal diferentes onde a câmera estará operando em um ambiente próximo à linha de visão (LOS), sem muitas ondas refletidas. Conduzimos um teste de transmissão externa e medimos o desempenho de transmissão externa do sistema MIMO proposto para esclarecer a possibilidade de uso da MiMoCam em ambiente externo. Este artigo apresenta os recursos do sistema MiMoCam e a técnica de transmissão MIMO usada no MiMoCam e apresenta os resultados deste teste externo. Também foi confirmado que a correlação de canal dos canais de propagação MIMO foi suprimida pelo uso de ondas polarizadas ortogonalmente e as características da taxa de erro de bit (BER) em relação à relação portadora-ruído (CNR) média de recepção foram melhoradas. Finalmente, pudemos encontrar a viabilidade da operação externa da MiMoCam a partir desses resultados.

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.
