Abstract :
By changing the propagation characteristics of the environment actively in some ways, we can obtain the better transmission performance of wireless communication channel. We call such method “Active Propagation Control” (APC). In this paper, we analyze the improvement effect of the transmission performance by APC in the case where the propagation characteristics are continually changed without any feedback from the receiver for the purpose of reducing the spatial dependency of the transmission characteristics caused by multipath fading. We change the indoor propagation characteristics by rotating a metal plate in a room and evaluate the changes of the characteristics by two-dimensional FDTD analysis. In the evaluation the improvement of SISO and MIMO channel capacity by APC is shown.
