We have been developing a wireless high-definition television (HDTV) camera called "millimeter-wave mobile camera". In this development, low-compression HDTV transmission with low latency and high link reliability is required, so an application of the multiple-input multiple-output (MIMO) technique and millimeter-wave band for the camera was examined. In this paper, to use the camera in a line-of-sight environment, the outdoor transmission performance of a MIMO multiplexing transmission device equipped with orthogonal polarized omnidirectional antennas was measured. In conclusion, it was confirmed that MIMO channel correlation was reduced to less than 0.45 and the BER performance became better.
