PROBLEM TO BE SOLVED: To obtain the sufficient effect of error correction due to error-correction decoding in a system where a plurality of sequence signals are generated by encoding using generation polynomials and an OFDM (Orthogonal Frequency Division Multiplexing) signal is transmitted by a MIMO (Multi Input Multi Output)-OFDM transmission system. SOLUTION: A terminal device 100 includes: an intra-code encoding section 113 for generating a plurality of sequence signals by performing encoding using a plurality of generation polynomials; and a transmission signal distributing section 114 for equally distributing each of the plurality of sequence signals generated by the encoding section 113. Thus, even when performance of an RF section of a specific transmission antenna 101 is deteriorated or specific propagation path characteristics are deteriorated, in a base station device 200 which receives an OFDM signal, there is no deviation between sequences in each of the sequence signals generated by encoding. Accordingly, the sufficient effect of error correction due to error-correction decoding can be obtained similarly to the case of ordinary SISO transmission. COPYRIGHT: (C)2010,JPO&INPIT
