ABSTRACT:
Radio receiving apparatus includes antennas, radio units adjusting gains of received signals, and outputting the adjusted received signals, respectively, converters converting the adjusted received signals into digital signals, selector device which selects several of the digital signals, combination of the selected digital signals exhibiting good receiving characteristic, controller which determines the gains and outputs single control signal included in information of the determined gains to certain radio units, the certain radio units being included in the radio units and connected to certain converters of the converters which output digital signals included in the selected combination, weight calculator which calculates weight for each of the selected digital signals to enhance the receiving characteristic if the controller outputs the single control signal, synthesizer which synthesizes, into synthetic digital signal, digital signals obtained by multiplying each of the selected digital signals by the weight, and demodulator which demodulates the synthetic digital signal.
