要約
(EN)

A wireless communication apparatus having a plurality of antennas 11-1 to 11-M and for diversity-combining signals received by the antennas 11-1 to 11-M, includes a first combining unit (23, 24) for combining received power of the antennas 11-1 to 11-M based on a first algorithm; a second combining unit (21-1 to 21-M, 22, 23) for combining received power of the antennas 11-1 to 11-M based on a second algorithm, which is different from the first algorithm; a determination unit 15 for determining whether there is a delayed wave based on the received signals; and a control unit 16 for selecting either one of the first combining unit (23, 24) and the second combining unit (21-1 to 21-M, 22, 23) depending on a determination result by the determination unit 15 and controlling a selected combining unit to combine received power of the antennas 11-1 to 11-M. Thus, it is possible to reduce the influence of multipath fading and maintain a constantly stable reception condition even when the number of reception antennas is small.
