ABSTRACT:
The second rate de-matching unit carries out a second rate de-matching step in parallel to each of two data defining the received data Rx for removing bits having been repeated in a second rate matching step having been carried out in a base station, or de-removing bits having been punctured in the second rate matching step having been carried out in a base station. The adders carry out a combining step in parallel in which data stored in the IR buffer is added to associated data among the two data. The first rate de-matching/turbo-decoding unit carries out a first rate de-matching step in which bits having been punctured in a first rate matching step having been carried out in a base station are repeated to data having been output from the input buffers, and simultaneously, repeatedly carries out a turbo-decoding step to the data.
