RADIO TRANSMISSION DEVICE, RADIO RECEPTION DEVICE, AND RADIO TRANSMISSION METHOD

摘要

There is provided a radio transmission device capable of increasing the diversity effect. In this device, a phase rotation unit (102) performs phase rotation processing of 26.6 degrees + 14.0 degrees = 40.6 degrees; a synthesis unit (107) performs IQ synthesis processing; an IQ separation unit (108) performs IQ separation processing; and interleavers (106, 111) performs interleave twice before and after the IQ synthesis processing and the IQ separation processing, so that the modulation symbol of the element obtained by a mapping unit (101) is distributed and arranged to a multinary modulation symbol which is higher by two ranks or more (for example, from a QPSK symbol to a 256QAM symbol).
