Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To dispense with a local oscillator from a slave unit by preparing a constitution in which a master unit transmits a non-spread signal and the slave unit receives the non-spread signal to transmit it to the master unit as a spread signal through the spread spectrum. SOLUTION: In a radio communication system, in particular that exchanges the information with a contactless card, a master unit 1 transmits the non-spread signals 1s of narrow bands to a slave unit 20. Upon receiving the signals 1s, the unit 20 applies the spread spectrum to some of the signals 1s and transmits them to the unit 1 as spread signals 20s of wide bands. Then the signals 20s are spreaded by a spread code corresponding to the individual information on the unit 20, and the unit 1 receives the signals 20s and applies inverse spread to them to acquire the spread signal that is used for the inverse spread, according to the presence or absence of correlation (i.e., the spread code used by the unit 20 for spread) and the acquire the individual information from the unit 20.  The unit 1 continuously transmits the signals 1s, until it ends the reception of signals 20s from the unit 20.
