摘要

MIMO transmitting apparatus to improve the transmission efficiency, MIMO receiving apparatus, MIMO transmission signal forming method, and MIMO transmission signal separation method. MIMO communication device (100), the mapping unit (120), with maps the transmit stream code blocks and code words, the first transmission of a transport block, the combination of the code blocks mapped to the same transmission period I want to change in the retransmission. MIMO communication device (200) to form an interference replica signal based on the decoded data of the code blocks that are successfully decoded, corresponding to the successfully decoded code blocks, the signal separation unit interference replica generation unit (260) is, (220 from the received plurality of streams received this time, after removing an interference replica signal formed interference replica generation section (260) upon receipt of the last previous) separates each stream receiving multiple streams received this time.
