CPC H04B 7/0691 (2013.01) [H04B 7/0617 (2013.01); H04B 7/0626 (2013.01)] | 8 Claims |
1. An antenna placement method in a system for detecting an object in a detection area between at least one set of a transmission station and a reception station by a wireless signal, the antenna placement method comprising:
a) making the transmission station having a plurality of antennas transmit a measurement signal for measuring channel state information;
b) making the reception station having a plurality of antennas measure the channel state information based on the measurement signal and notify a detection server of a result of the measurement; and
c) making the detection server perform processing where the detection server detects an object based on the channel state information, calculates at least one of a channel capacity and an eigenvalue distribution based on a propagation channel matrix between the transmission station and the reception station,
d) changing position of at least one antenna associated with the transmission station or the reception station to yield a plurality of antenna arrangements, and repeating step a)-d) for multiple iterations; and
selecting an antenna arrangement from amongst the plurality of antenna arrangements where the channel capacity becomes a largest, thereby tailoring the antenna arrangement to detect the object.
