摘要：<p>An RV pattern selecting part (102) has stored therein at least two RV parameter tables for QPSK and for 16QAM, selects, based on the correspondence between an estimated number of transmissions inputted from a number-of-transmissions estimating part (101) and an input Doppler frequency (fD) as estimated from a transmission signal, a corresponding RV parameter (Xrv) (e.g., RV_a_T1) from the RV parameter tables, and outputs the selected RV parameter to a channel encoding part (103). In this way, an RV parameter, which corresponds to an appropriate number of transmissions with the affection of the Doppler frequency taken into account, can be set, and further, a transmission bit pattern corresponding to a change in the Doppler frequency of the transmission signal can be set, whereby the number of transmissions can be reduced.</p>
