Summary:In multiple-input multiple-output (MIMO) systems, we need the scheme that attains high quality and high throughput data transmission. We proposed the throughput maximization transmission control scheme (TMTC) for MIMO systems. The proposed transmission control scheme selects a transmission scheme with maximum transmission rate based on signal to interference and noise ratio (SINR) and signal to noise ratio (SNR). In time-varying channels, however, the selected transmission scheme fed back to the transmitter becomes outdated. That is, there is a mismatch between "the selected transmission scheme at the receiver" and "the optimum transmission scheme at the transmitter." Therefore, the throughput performance of TMTC may decrease. In this paper, we propose TMTC using a minimum-mean square error (MMSE) channel prediction for MIMO systems. From the computer simulation, we show that even when the large feedback delay exists, the proposed scheme attains high throughput
