- 論文の詳細を見る
MIMO (multiple-input multiple-output) transmission is a promising technology to improve the frequency usage efficiency in mobile radio communications. In this letter, MIMO transmission with eigenbeam space division multiplexing (E-SDM) is focused on and the site-dependent beamforming characteristics is examined to know the transmission characteristics. Site-dependent radiowave direction of arrival and impulse responses are obtained using ray tracing. Result shows that effect of radiowaves with longer delays is enhanced due to E-SDM beamforming, and rather more capability of treating a longer excess delay is necessary for time-domain multipath compensation.
