<P>PROBLEM TO BE SOLVED: To provide a bidirectional radio system in which it is not necessary to construct an ID identification system on user side, and increase in processing time and power consumption is suppressed, without causing deterioration in the transfer efficiency. <P>SOLUTION: In the bidirectional radio system, a transmitting-side radio device transmits a synchronization code and a synchronization word of a synchronizing part in a radio frame and system information of a data part as an ID code; a receiving-side radio device detects a correlation peak by using the synchronization code; establishes synchronism using the synchronization word; performs ID identification by using the synchronizing code, the synchronizing word and the system information as the ID code; and receives the data of a user, when identification is made. <P>COPYRIGHT: (C)2010,JPO&INPIT |
