摘要：
In a radio information communication system of this invention, at least part of a transmission data string is first divided into a plurality of bit strings when data is transmitted by radio in a radio station on the transmission side and a plurality of carrier waves of different frequencies are subjected to primary modulation by the divided bit strings. Then, the primary-modulated carrier waves are subjected to secondary modulation by the spread spectrum system such as the frequency hopping system or chirp system and modulated waves obtained by the secondary modulation are transmitted.
