| Abstract(in English) | This paper proposes a new method for predicting the propagation characteristics between each transmitting and receiving antenna composing antenna arrays. For the purpose of decreasing the calculation load, the ray-tracing calculation is conducted using the selected transmitting and receiving gravity point for deriving reflected and diffracted points. These derived reflected and diffracted points are shared for the ray-tracing calculation against the all other combinations of transmitting and receiving antenna comprising antenna arrays. The effect of the proposed method is evaluated by comparing between the ray-tracing calculation results using proposed method and precise method for a simple outdoor environment. The effectiveness of the proposed method for predicting the MIMO propagation characteristics for systems using antenna arrays are shown in terms of the differences of the eigenvalue calculated by MIMO correlation matrix between using original precise method and proposed method. |
