Abstract:
1. An antenna array system, comprising: an antenna array which includes a plurality of antenna elements; a signal detection section which detects base station signals including desired signals and interference signals from among received signals received by the respective antenna elements; a control section which selects one or more desired signals and one or more interference signals to be cancelled from detected signals; a spatial signature detection section which detects spatial signatures of the desired signals and the interference signals to be cancelled from the received signals; a virtual-signal generation section which generates one or more virtual-signals, the number of which is equal to the number of interference signals to be cancelled, based on the spatial signature of the interference signals to be cancelled; an array weight generation section which generates array weights for the respective antenna elements based on the virtual-signals and the spatial signatures of the desired signals; and a signal combining section which performs weighting for the received signals received by the respective antenna elements using the array weights and combines the weighted received signals to output a resultant combined signal.
