Abstract
A base station according to this disclosure includes a plurality of antennas used for transmission and reception, an adaptive array processing unit that performs adaptive array processing on reception signals received by the plurality of antennas, and a control unit that decides a transmission antenna used for the transmission from the plurality of antennas at a time when a transmission signal is transmitted, and the control unit decides the transmission antenna based on transmission weight vectors respectively corresponding to the plurality of antennas obtained from a processing result of the adaptive array processing unit.
Claims4
A base station comprising:
- a plurality of antennas used for transmission and reception;
- an adaptive array processing circuit that performs adaptive array processing on reception signals received by the plurality of antennas;
- and
- a control circuit that decides a transmission antenna used for the transmission from the plurality of antennas at a time when a transmission signal is transmitted, wherein
- the control circuit decides the transmission antenna based on transmission weight vectors respectively corresponding to the plurality of antennas obtained from a processing result of the adaptive array processing circuit, wherein
- in a case where a difference between each of reception levels when the reception is performed by the plurality of antennas is within a reference, the control circuit decides an antenna corresponding to a largest reception level among each of the reception levels as the transmission antenna.
A transmission antenna deciding method in a base station including a plurality of antennas used for transmission and reception, the transmission antenna deciding method comprising:
- performing adaptive array processing on reception signals received by the plurality of antennas;
- deciding a transmission antenna used for the transmission from the plurality of antennas at a time when a transmission signal is transmitted;
- and
- deciding the transmission antenna based on transmission weight vectors respectively corresponding to the plurality of antennas obtained from a processing result of the adaptive array processing, wherein
- deciding the transmission antenna includes:
- in a case where a difference between each of reception levels when the reception is performed by the plurality of antennas is within a reference, deciding an antenna corresponding to a largest reception level among each of the reception levels as the transmission antenna.
