Summary:
A conventional adaptive array antenna system needs the analog circuits, such as the filter, amplifier, down converter and AD converter, for each antenna. Accordingly, it is a problem that the scale of the analog circuits for the conventional adaptive array antenna system is larger than the one for the single antenna system. In the past study, the method of scale reduction of the analog circuits, which are time-division multiplexed and shares the parts except the amplifier and the filter, was proposed. In that study, the separation technique for the mixtures of the each antenna's signal, caused by the extension of switch-on time, was formulated. In the next study, we proposed the method of signal-to-noise ratio improvement by the optimization of the switching order according to the received signals. Nevertheless, that method was inspected in the condition of the receiving signals from the particular directions. In this study, the method of the switching order optimization in the situation of the receiving signal from the all directions is examined. Via computer simulation, it is confirmed by the comparison with the conventional method that our proposed method is effective.
