Abstract (in Japanese) (See Japanese page) 
(in English) In multi-input multi-output (MIMO) space division multiplexing (SDM) systems based on transmit-
ter/receiver spatial ltering, a transmitter weight optimization method under constraint of per-antenna maximum
transmit power has been investigated. In this paper, we evaluate performance of a transmit peak power aware
MIMO SDM systems under time-varying channels, where we assume frequency division duplex (FDD) systems and
apply a method that the receiver send back the difference between channel estimates of current and previous ones.
We also investigate a method that the receiver send back the difference between weights currently used at the trans-
mitter and optimum ones calculated at the receiver. Computer simulation results show that the above feedback
type weight control techniques are effective for mitigating the in
uence of channel variation, while transmit peak
power is reduced.
