<p><P>PROBLEM TO BE SOLVED: To provide an OFDM radio communication device which can secure a security of a radio communication within a radio communication system, since a prior art OFDM radio communication device depends on things such as secret of data by encryption and an authentication of a device/user other than the radio communication system with respect to the security of the radio communication. <P>SOLUTION: The OFDM radio communication device has serial/parallel conversion circuits 6a-6d adopting different data conversion methods respectively and parallel/serial conversion circuits 18a-18d adopting different data conversion methods respectively. An operation circuit 24 generates a selection signal by using a code, GPS time information, key information, and the like. Based on the selection signal, the serial/parallel conversion circuits 6a-6d and the parallel/serial conversion circuits 18a-18d are selected. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
