Summary:PROBLEM TO BE SOLVED: To obtain a radio communication system which suppresses interference wave components and largely improves decoding performance even when a transmission reception antenna is configured by the number of antennas other than the number of exponentiation of 2. SOLUTION: A data transmission apparatus 1 includes an error correction encoding unit 11 for producing a code word by performing error correction encoding about data, a modulation unit 12 for modulating the code word, and a code word transmitting means for dividing the modulated code word and simultaneously transmitting a plurality of divided code words using transmission antennas 16a to 16f, wherein encoding is performed to allow decoding removing the interference component of transmission data. The data reception apparatus 2 includes an MIMO processing unit 22 for receiving a plurality of code words to be transmitted simultaneously using reception antennas 21a to 21f, and a demodulating means for integrating a plurality of code words and demodulating the code word after integration, wherein data before encoding by the data transmission apparatus 1 is reproduced using the code word transmitted from the data transmission apparatus 1.
