Abstract
In this paper, in order to research spectrum usage efficiency in urban canyon environment at the microwave band, measurement and channel capacity analysis of multi-antenna technology is described. The measurement data obtained from 3 - 4 stories building area used and the propagation characteristics at the 3.7 and 8GHz band are analysed and compared. In case of $2{\times}2$ MIMO, channel capacities of 3.7 and 8 GHz band are calculated to 9.1 bps/Hz and S bps/Hz and in case of $4{\times}4$ MIMO, 21 bps/Hz and 12.5 bps/Hz respectively. Considering the coverage, SNR and channel capacity in urban environment, MIMO propagation characteristics of 3.7 GHz are more predominate than those of 8 GHz.
