要約
(EN)
Provided is a radio communication device which has a plurality of antennas (11-1 to 11-M) and diversity-synthesizes reception signals of the antennas (11-1 to 11-M). The radio communication device includes: first synthesis units (23, 24) which synthesize the reception powers of the antennas (11-1 to 11-M) according to a first algorithm; second synthesis units (21-1 to 21-M, 22, 23) which synthesize the reception powers of the antennas (11-1 to 11-M) according to a second algorithm which is different from the first algorithm; a judgment unit (15) which judges whether a delay wave is present according to the reception signals; and a control unit (16) which selects the first synthesis units (23, 24) or the second synthesis units (21-1 to 21-M, 22, 23) according to the judgment result made by the judgment unit (15), so as to synthesize the reception powers of the antennas (11-1 to 11-M). Thus, it is possible to reduce the affect of the multi-fading and always maintain a stable reception state even by using a small number of reception antennas.

提供了具有多个天线(11-1至11-M)并对多个天线(11-1至11-M)接收信号进行分集合成的无线通信设备。该无线通信设备包括:第一合成单元(23、24),用于根据第一算法对天线(11-1至11-M)的接收功率进行合成;第二合成单元(21-1至21-M、22、23),用于根据不同于第一算法的第二算法对天线(11-1至11-M)的接收功率进行合成;判断单元(15),用于根据接收到的信号确定是否有延迟波;以及控制单元(16),用于根据判断单元(15)的判断结果选择第一合成单元(23、24)或第二合成单元(21-1至21-M、22、23),以使得可以对天线(11-1至11-M)的接收功率进行合成。从而,可以降低多衰落的影响,并且即使使用了数量少的接收天线,也总是维持稳定的接收状态。
