A wireless communication system characterised by comprising: transmitting means configured to transmit a first data sequence, from among a plurality of data sequences obtained by turbo encoding, via a first radio transmission path different from a second radio transmission path that is configured to transmit a second data sequence from among the plurality of data sequences obtained by turbo encoding; and receiving means for receiving the first data sequence via the first radio transmission path and the second data sequence via the second radio transmission path different from the first radio transmission path, wherein the first data sequence is user data, and the second data sequence is a primary error correction code generated by the turbo encoding of the user data; the first radio transmission path includes a first base station unit (13a, 14a) configured to transmit encoded user data to the receiving means, wherein the encoded user data is obtained by the first base station unit (13a, 14a) by subjecting the user data received from the transmitting means to secondary error correction encoding processing; the second radio transmission path includes a second base station unit (13b, 14b) configured to transmit encoded primary error correction code to the receiving means, wherein the encoded primary error correction code is obtained by the second base station unit (13b, 14b) by subjecting the primary error correction code to secondary error correction encoding processing; and the receiving means is configured to subject the encoded user data received from the first base station unit (13a, 14a) to secondary error correction processing to obtain decoded user data, to subject the encoded primary error correction code received from the second base station unit (13b, 14b) to secondary error correction processing to obtain decoded primary error correction code, and then to subject the decoded user data to error correction processing using the decoded primary error correction code. transmitting means configured to transmit a first data sequence, from among a plurality of data sequences obtained by turbo encoding, via a first radio transmission path different from a second radio transmission path that is configured to transmit a second data sequence from among the plurality of data sequences obtained by turbo encoding; and receiving means for receiving the first data sequence via the first radio transmission path and the second data sequence via the second radio transmission path different from the first radio transmission path, wherein the first data sequence is user data, and the second data sequence is a primary error correction code generated by the turbo encoding of the user data; the first radio transmission path includes a first base station unit (13a, 14a) configured to transmit encoded user data to the receiving means, wherein the encoded user data is obtained by the first base station unit (13a, 14a) by subjecting the user data received from the transmitting means to secondary error correction encoding processing; the second radio transmission path includes a second base station unit (13b, 14b) configured to transmit encoded primary error correction code to the receiving means, wherein the encoded primary error correction code is obtained by the second base station unit (13b, 14b) by subjecting the primary error correction code to secondary error correction encoding processing; and the receiving means is configured to subject the encoded user data received from the first base station unit (13a, 14a) to secondary error correction processing to obtain decoded user data, to subject the encoded primary error correction code received from the second base station unit (13b, 14b) to secondary error correction processing to obtain decoded primary error correction code, and then to subject the decoded user data to error correction processing using the decoded primary error correction code.
