Abstract (in Japanese) (See Japanese page) 
(in English) A downlink multi-user MIMO system uses a block diagonalization scheme to suppress inter-user interference. Furthermore, the system can realize efficient transmission using eigenbeam-space division multiplexing. In time-varying environments, however, bit error rate (BER) performance seriously degrades because MIMO channels change during the time interval between transmission parameter determination and actual MIMO transmission. Channel prediction techniques have been proposed to improve the BER performance in dynamic environments. In this paper, based on indoor measurement data, we evaluate the BER performance of the downlink multiuser MIMO system with linear extrapolation and second order extrapolation.
