摘要:
A base station allowing mobile stations to efficiently remove interference signals. In this base station (100), an encoding part (101) performs an error correction encoding of transport data to generate a bit sequence comprising systematic bits and parity bits; a repetition part (102) repeats, as a repetition subject, only the parity bits out of the plurality of bits included in the bit sequence, which is generated by the encoding part (101), so as to perform a rate matching; a modulating part (103) modulates, after the repetition, the bit sequence to generate symbols; an S/P part (104) parallel converts the symbols serially inputted from the modulating part (103) and then outputs them to an IFFT part (105); and the IFFT part (105) performs an IFFT processing of the symbols inputted from the S/P part (104) and then maps them onto subcarriers in accordance with a predetermined mapping pattern, thereby generating OFDM symbols.
