ABSTRACT:
A transmitting apparatus capable of enhancing the certainty of data transmission of MIMO system, improving the system throughput, and providing a retransmission technique adaptive to the multi-antenna transmission. In this apparatus, a serial/parallel converting part (300) serial/parallel converts the data, which is to be transmitted, into a number nTof data substreams. A data rearranging part (301) rearranges, based on feedback information, the nTdata substreams. CRC encoding parts (302) CRC encode the respective data substreams. Modulating/encoding parts (303) modulate and encode the respective corresponding data substreams. A number nTof transmission antennas (304) transmit the data substreams.
