When the determination result from the determination unit
15 is that “there is a delayed wave”, on the contrary, the control unit
16 controls the switches
26-
1 to
26-M and the switches
27-
1 to
27-M so that the outputs from the reception units
12-
1 to
12-M are provided to the combining circuit
23 via the corresponding equalizers
21-
1 to
21-M, and also controls the switch
29 and the switch
30 so that the output from the combining circuit
23 is provided to the decode unit
14 with bypassing the equalizer
24. Furthermore, the control unit
16 turns on the ON/OFF switch
28 so that the antenna reliability ratio is provided from the combining weight generation circuit
22 to the combining circuit
23, and turns off the ON/OFF switch
31 to block the reliability information output line from the equalizer
24 to the decode unit
14. Thus, the combining circuit
23 generates a combined reception signal based on the antenna reliability ratio.
