RADIO TRANSMISSION DEVICE AND RADIO TRANSMISSION METHOD

摘要

An RV pattern selection section (103) contains at least two RV parameter tables: one for QPSK and the other for 16QAM. According to the correspondence relationship between an estimated transmission count input from a transmission count estimation section (101) and an encoding ratio input from an encoding ratio calculation section (102), the RV pattern selection section (103) selects a corresponding RV parameter Xrv from the RV parameter tables and outputs it to a channel encoding section (104). According to the RV parameter Xrv input from the RV pattern selection section (103), the channel encoding section (104) modifies the rate matching pattern of the transmission data and the constellation rearrangement (applied only to the 16QAM).
