In MIMO systems, it has been reported that MMSE precoder weighting transmitted signals based on MMSE criterion at the transmitter using feedback channel state information (CSI) achives good performance.
Throughput maximization transmission control scheme that selects transmission scheme (modulation schemes and code rates) based on CSI has been proposed. We expect that throughput performance is improved by applying MMSE precoder to the throughput maximization transmission control scheme. However, throughput performance is degraded in the presence of feedback delay.
In this report, we propose the throughput maximization transmission control scheme using MMSE precoder that reduces throughput performance degradation by using channel prediction and receive weight robust to feedback delay.
The proposed scheme selects transmission scheme (the number of substreams, modulation schemes, and code rates) and designs the precoder with miximum throughput based on SINR predicted by channel prediction. Simulation results show that even when the feedback delay exists, the proposed scheme attains high throughput. |
