<p>A radio transmitter, a radio receiver, a radio communication system, a method for controlling radio signals are provided to distinguish a group, to which a received signal belongs, without performing complicated data demodulation processing for the received signal, in an environment where a plurality of groups exist. A radio transmitter(1) comprises an ID signal housing unit(21), a data modulation unit(22), a radio signal ID allocating unit(23), and a radio signal transmitting unit(24). The ID signal housing unit(21) stores ID signals for identifying groups to which transmitted data signals belong respectively. The data modulation unit(22) modulates a data signal. The radio signal ID allocating unit(23) associates the modulated signal with an ID signal stored in the ID signal housing unit(21), grants a high-degree statistical feature corresponding to the ID signal to the modulated signal, and creates a signal to be transmitted. The radio signal transmitting unit(24) transmits the created signal by wireless.</p> |
