DECODER AND DECODING METHOD

摘要

A candidate limiting section (104) outputs only a TFCI coded series corresponding to the actually usable TFCI number to a correlation calculating section (105) according to the TFCI numbers included in a TFCI number group sent from an upper layer above a physical layer. The correlation calculating section (105) calculates the correlation between the coded series outputted from the candidate limiting section (104) and the received TFCI and stores it in a correlation memory (106). A maximum detecting section (107) sends the TFCI number corresponding to the correlation taking on the maximum out of the correlation stored in the correlation memory (106) to an error-correction decoding section (108). The error-correction decoding section (108) subjects the data stored in a data memory (103) to error-correction decoding according to the transmission format specified by the sent TFCI number.
