| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In high-speed mobile OFDM communication systems, receiving characteristics degrade significantly due to time variation of the channel properties. One solution is to rotate a circular array antenna so as to decrease the speed of receiving antenna relative to the ground. When the vehicle speed changes, the rotating antenna needs to keep the optimum rotation speed. To solve this problem, we proposed a control method of the rotating antenna. The steepest descent method based on the MSE of the demodulation output before and after of the vehicle speed changes is adopted to update the rotation speed. However, performance of this method is dropped since MSE behaves in an erratic characteristic by noise and fading. In this paper, we propose a new method to control rotation speed using a moving average filter. Simulation results show the effectiveness of the proposed method. |
