    • 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.
    • 基站允许移动台有效地去除干扰信号。 在该基站(100)中,编码部(101)进行传输数据的纠错编码,生成包含系统比特和奇偶校验位的比特序列; 重复部分(102)作为重复对象重复由编码部分(101)生成的比特序列中包括的多个比特中的奇偶校验位,以便执行速率匹配; 调制部分(103)在重复之后调制比特序列以产生符号; S / P部分(104)并行转换从调制部分(103)串行输入的符号,然后将其输出到IFFT部分(105); 并且IFFT部分(105)对从S / P部分(104)输入的符号进行IFFT处理,然后根据预定的映射模式将它们映射到子载波上,从而生成OFDM符号。
