RADIO TRANSMITTING APPARATUS, RADIO RECEIVING APPARATUS AND RADIO TRANSMITTING METHOD

摘要

A radio transmitting apparatus, a radio receiving apparatus and a radio transmitting method wherein the accuracy of detecting streams in D-TxAA is improved. There is included a transmission mode switching part (102) that switches output destinations of first and second input streams (1865,1866) in accordance with the propagation environments of first and second MIMO channel beams (1831,1832). The transmission mode switching part (102) switches from a D-TxAA mode transmission to a first or second unique mode transmission in accordance with the propagation environments.
