<p><P>PROBLEM TO BE SOLVED: To conduct a change or a setting of a carrier in a system from a communication error data at a carrier sense time. <P>SOLUTION: A radio communication apparatus is provided with a counter 16a to count a carrier sense frequency, a receiving data comparing circuit 14 to compare a prescribed information in a receiving signal with an information set in advance, counters 16b to 16d to count a coincidence frequency or an anticoincidence frequency, a RAM 30c to store the counted results of each counter 16a to 16d, and a microcomputer 30 to judge whether the change of the carrier is permitted or not, from a ratio of the carrier sense frequency to the coincidence frequency or the anticoincidence frequency. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
