<P>PROBLEM TO BE SOLVED: To provide a HSDPA receiver and a rate dematching processing method for reducing a rate dematching processing time so as to improve the throughput through the reduction in the processing time. <P>SOLUTION: The HSDPA receiver includes a rate dematching processing section 1-2 for executing first rate dematching processing and second rate dematching processing, the rate dematching processing section 1-2 stops the first rate dematching processing at an output of a derepetition signal detected in the second rate dematching processing, stops the second rate dematching processing at an output of a signal delayed by one bit of a depuncture signal detected by the first rate dematching processing, and executes the first rate dematching processing and the second rate dematching processing in parallel at the same time. Further, a HARQ composite section 1-3 executes composite processing of received data by a hybrid automatic repeat request (HARQ) in parallel at the same time of the rate dematching processes. <P>COPYRIGHT: (C)2008,JPO&INPIT |
