| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In multi-input multi-output (MIMO) space division multiplexing (SDM) systems based on transmitter/receiver spatial filtering, 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 channel estimates currently used at the transmitter and optimum ones calculated at the receiver. Computer simulation results show that the above feedback type weight control techniques are effective for mitigating the influence of channel variation, while transmit peak power is reduced. |
