<P>PROBLEM TO BE SOLVED: To provide a radio base station device which improves efficiency in using resources for decoding processing. <P>SOLUTION: The present invention relates to a radio base station device which receives communication data from a mobile unit and performs decoding processing thereon, the communication data resulting from encoding and multiplexing communication object information and communication control information through a spreading techniques, including: a communication object information decoding section for decoding the encoded communication object information; a correlation value calculating section for calculating and sending out a maximum value of correlation of a despread communication control information; a reliability calculating section for comparing a value, for each symbol regarding communication control information prior to correlation value calculation, with communication control information resulting from re-encoding despread communication control information using the maximum value of correlation, and for sending out, as reliability information, a numerical value corresponding to a ratio of the number of matching symbols in the number of symbols to be compared; and a decoding implementation control section which compares the reliability information with a first threshold when the reliability information is received from the reliability calculating section, and sends out control information for executing decoding processing of the communication target information to the communication target information decoding section if the reliability information is equal to or higher than the first threshold. <P>COPYRIGHT: (C)2008,JPO&INPIT |
