Abstract:
1. A coded division multiple access (CDMA) receiver for use with a CDMA mobile communication system, comprising: transport format combination indicator (TFCI) decoding means for obtaining correlation values between a TFCI signal associated with transfer format information of data and a predetermined TFCI code sequence; and TFCI correlation judging means for comparing a first threshold value with a correlation value distance represented by a difference between a TFCI correlation value of a TFCI candidate having a largest TFCI correlation value obtained by the TFCI decoding means and a TFCI correlation value of a TFCI candidate having a next largest TFCI correlation value obtained by the TFCI decoding means and conducting a control operation in which when the correlation value distance is less than the first threshold value, decoding processing of decoding data of a physical channel into a data of a transport channel according to the transport format information of the TFCI candidate is concurrently executed using transport format information items of a plurality of TFCI candidates, wherein when the correlation value distance is less than the first threshold value, the decoding processing is concurrently executed using transport format information items of the TFCI candidates, the receiver further comprising transport channel format judging means for making a check to determine whether or not a cyclic redundancy check (CRC) judge result obtained from the decoding processing is normal and reporting to a higher layer the CRC judge result and data of a transfer channel obtained by decoding data of a physical channel according to transfer format information associated with a TFCI candidate for which the CRC judge result is normal.
