抄録(英) | For wireless communications with a limited amount of bandwidth, more spectrum efficient techniques are required. Space division multiplexing (SDM) is one of the most promising techniques for achieving more efficient bandwidth utilization, since it enable the transmission rate over MIMO channels to be increased by using multiple antennas on both the transmitter and receiver sides. Recently, since cost of RF is much higher than the antennas, there is growing interest in techniques that use larger number of antennas than the number of transmitter RF. These methods rely on selecting the optimal transmitter antennas and connecting them to respective RF. In this case, the FBI is required to select the optimal transmitter antennas. However, transmission of the FBI through a feedback channel is limited. Moreover, multiple antennas system requires an antenna separation of 5-10 wavelength to keep the correlation coefficient below 0.7 for achieving the diversity gain. In this case, base station is required a wide space to set the multiple antenna. To reduce these problems, in this paper, we propose and analyze the transmit sector antenna selection with considering the link correlation for SDM/OFDM without FBI. |
