To provide with simple configuration a diversity receiver in which a cost is reduced.

Signals received by antennas 1 and 2 outputs values in proportion to the logarithm of a baseband signal and a reception signal field strength indicator (RSSI) in receiving parts 3 and 4. The baseband signals from the receiving parts 3 and 4 are digitized through an A/D converter 5. Weighting is selected by weighting tables 23 and 24, is accordance with RSSI, weighting is executed in the baseband signals by bit shifters 25 and 26 and, then they are synthesized and outputted. A weighting part consists only of an adder 10 and a bit shift 25, so that configuration is simplified and cost is reduced.
