RADIO COMMUNICATION APPARATUS, TRANSMITTER APPARATUS, RECEIVER APPARATUS AND RADIO COMMUNICATION SYSTEM

摘要

For example, a channel division part (1) in the radio communication apparatus on a transmitting side divides, based on "channel structure information indicative of MIMO channel structure method" notified from the radio communication apparatus on a receiving side, a transmitted signal into a plurality of channels. An STC part (4) performs an STC (Space Time Coding) processing for each divided channel to realize transmission diversity, while a transmission path estimation part (15) in the radio communication apparatus on the receiving side estimates a transmission path between the transmitting and receiving sides. A transmitting-side channel structure decision part (20) decides, based on a result of that transmission path estimation, a physical structure of the radio communication apparatus on the transmitting side and a physical structure of the radio communication apparatus on the receiving side, the MIMO channel structure, and then notifies the radio communication apparatus on the transmitting side of a result of that decision, that is, the channel structure information.
