摘要：Aircraft seems to be the last isolated island where
the wireless access is still not available. In this paper, we consider
the distributed multiple-input multiple-output (D-MIMO) system
application based on measurements in aircraft cabin. The channel
response matrices of in-cabin D-MIMO system are collected
by using a wideband channel sounder. Channel capacities with
optimum transmit antenna selections (TASs) are calculated from
the measured data at different receiver positions. Then the
optimum capacity results are compared to those without selection
in different transmit SNR. It is shown that the TAS can lead
obvious capacity gain, especially in the front and back of cabin.
The capacity gain represents a decreasing trend with the transmit
SNR increasing. The optimal transmit antenna subset is closely
related to the transmit SNR. With the SNR increasing, more
transmit antennas will be chosen for higher performance. The
subset of those transmit antennas near the receiver is a reasonable
choice in practical application of D-MIMO system.
