Abstract:
1. An antenna selection method, comprising: utilizing each of a plurality of antennas to receive a plurality of transmission signals from a plurality of stations, respectively; generating a plurality of reception signals according to the plurality of transmission signals by a signal conversion unit; estimating a plurality of signal quality indicators corresponding to the plurality of stations according to the plurality of reception signals for each of the plurality of antennas, respectively, by a signal quality estimation unit; calculating a weighted sum of the plurality of signal quality indicators to generate a calculation result for each of the plurality of antennas by a signal calculation unit; and selecting a receiving antenna from the plurality of antennas according to the corresponding calculation result of each of the plurality of antennas, respectively, by a decision unit; wherein the plurality of antennas comprise at least a first antenna and a second antenna, and the step of calculating a weighted sum of the plurality of signal quality indicators to generate a calculation result for each of the plurality of antennas, comprise: calculating a first weighted sum of a plurality of signal quality indicators respectively corresponding to the plurality of stations for the first antenna to generate a first calculation result for the first antenna; and, calculating a second weighted sum of a plurality of signal quality indicators respectively corresponding to the plurality of stations for the second antenna to generate a second calculation result for the second antenna.
