Abstract (in Japanese) (See Japanese page) 
(in English) Multi-Input-Multi-Output (MIMO) is an emerging technology for the 4th-generation mobile communication systems due to the capability of high-speed data transmission. There have been only a few literatures about MIMO propagation characteristics under outdoor condition, and most of which have focused only on 2 GHz bands for existing cellular systems. However, since 3.4-3.6GHz band has been allocated as one of frequency bands for the 4th-generation mobile communication systems, the channel characteristics at this band should be carefully considered. This report presents the outdoor MIMO channel characteristics measured by a 2×2 MIMO channel sounding system at the center frequency of 3.35GHz in urban environment. In this measurement system, the 9-stage PN signals are transmitted by controlling the transmission timing in each transmitter, and hence, the complex MIMO channel impulse responses can be obtained by same PN sequence. We computed the channel capacity based on each eigenvalue that was obtained through singular value decomposition (SVD). Again, we compared the channel capacity for line-of-site (LOS) and non-line-of-site (NLOS) environments varying the distance between antennas.
