摘要

通过某种方式主动改变环境的传播特性，可以获得较好的无线通信信道传输性能。我们称这种方法为“主动传播控制”(APC)。本文分析了在没有接收端反馈的情况下，在传输特性不断变化的情况下，APC对传输性能的改善效果，以降低多径衰落引起的传输特性的空间依赖性。我们通过在室内旋转金属板来改变其室内传播特性，并通过二维时域有限差分分析来评估其特性的变化。在评价中，给出了APC对SISO和MIMO信道容量的改善效果。

Study of channel capacity improvement by open loop active propagation control

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.
