The eigenmode transmission and the dominant eigenmode transmission (DET) can achieve a large channel capacity by utilizing the channel state information (CSI) both at the transmitter and the receiver. However, when channels are correlated, some of received antennas are subjected to a reduced received power due to low singular values. As a result, the bit error rate (BER) performance of the overall system is degraded. In this paper, we propose a space-orthogonalized eigenmode transmission (SOET) scheme which can prevent the degradation of the BER performance under correlated MIMO channels. In the SOET, MIMO channels are partitioned into several groups of uncorrelated MIMO channels so that the correlated channels belong to separate groups. In each group, DET is used. At the receiver, signals transmitted through MIMO channels within a group are decoded, and the resultant signals are maximum ratio combined. From simulation results, we show that the BER performance of the SOET is better than those of the conventional eigenmode transmission and antenna selection method under correlated MIMO channels. |
