Abstract:
1. A radio receiving method comprising: preparing a plurality of antennas; preparing a plurality of radio units adjusting gains of received signals output from the antennas, and outputting the adjusted received signals, respectively; preparing a plurality of converters converting the adjusted received signals into a plurality of digital signals; selecting several of the digital signals, a combination of the selected digital signals exhibiting a good receiving characteristic; determining the gains and outputting a 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; calculating a weight for each of the selected digital signals to enhance the receiving characteristic if the single control signal is output; synthesizing, into a synthetic digital signal, a plurality of digital signals obtained by multiplying each of the selected digital signals by the weight; and demodulating the synthetic digital signal.
