PROBLEM TO BE SOLVED: To simplify the configuration of the diversity receiver in mobile communication where a fading frequency is very low in comparison with a transmission rate. SOLUTION: Phase error measurement devices 31, 32 measure phase errors D31, D32, as to a base band signal outputted from a receiver, integration devices 41, 42 integrate phase errors D31, D32 outputted from the phase error measurement devices 31, 32 over a prescribed time range and output phase error integral values D41, D42. A weighting coefficient calculation device 50 uses the phase error integral values D41, D42 outputted from the integration devices, 41 42 to calculate weighting coefficients D51, D52 with respect to the base band signal, a synthesis computing unit 60 applies weighting coefficients D51, D52, to the base band signal, outputted from the weighting coefficient calculation device 50 to calculate the weighted base band signals and to synthesize them thereby outputting a synthesized base band signal D63. |
