提出了一种基于可调谐无源中继器的多输入多输出（MIMO）信道控制方法。无源中继器具有多个天线，并且每个天线具有移相器功能。通过单独控制无源中继器中的所有元件来最大化MIMO信道容量。所提出的无源中继器的有效性进行了评估数值和实验。从这些结果中发现，由于无源中继器的可调谐性，MIMO信道容量可以提高约40%。
A Multiple-Input-Multiple-Output (MIMO) channel manipulation using tunable passive repeater is presented in this paper. The passive repeater has multiple antennas and each of them has a phase-shifter function. The MIMO channel capacity is maximized by controlling all elements individually in the passive repeater. The effectiveness of the proposed passive repeater is evaluated numerically and experimentally. From these results, it is found that the MIMO channel capacity can be improved by about 40 % due to the tunability of the passive repeater.
