Abstract
A MIMO transmitting apparatus that achieves a flexible control in accordance with variation of a propagation environment to reduce the number of retransmissions is disclosed. An intra-code-word interleaver performs an interleave process on bits included in symbols to be simultaneously transmitted from a plurality of transmitting antennas. When performing the intra-code-word interleave process, the intra-code-word interleaver performs the interleave process in accordance with an interleave pattern notified from an interleave pattern table. A counter counts a number of retransmission requests, and outputs the number of retransmission requests to the interleave pattern table. The interleave pattern table stores interleave patterns to be used for the intra-code-word interleave process for the respective numbers of retransmission requests, and notifies the intra-code-word interleaver of an interleave pattern in accordance with the number of retransmission requests.
