Abstract:
1. A communication apparatus comprising: a signal reception unit that receives a wireless signal by a plurality of antennas; a measurement unit that measures a reception quality of each of the plurality of antennas according to the wireless signal received by the signal reception unit; an antenna selection control unit that switches a selection of the plurality of antennas by time-division, wherein the antenna selection control unit periodically switches the plurality of antennas and also specifies the antenna with the best reception quality of the plurality of antennas to have a relatively longer selected period than others of the plurality of antennas according to the reception quality measured by the measurement unit; and a signal level control unit that controls a signal level of the wireless signal received by the signal reception unit from a first antenna to be substantially equivalent to the signal level of the wireless signal received by the signal reception unit from a different antenna, the first antenna and the different antenna being included in the plurality of antennas; wherein the signal level immediately before switching the first antenna to the different antenna is held and the signal level is controlled according to the held signal level immediately after switching from the different antenna to the first antenna.
