Abstract
Provided is a radio communication device which can separate propagation paths of antenna ports and improve a channel estimation accuracy even when using virtual antennas. The device includes: a mapping unit which maps a data signal after modulation to a virtual antenna and a virtual antenna; a phase inversion unit which inverts the phase of Stransmitted from an antenna port in synchronization with a phase inversion unit between the odd-number slot and the even-number slot; the phase inversion unit which inverts the phase of Rtransmitted from the antenna port; a phase inversion unit which inverts the phase of Stransmitted from an antenna port in synchronization with a phase inversion unit; and the phase inversion unit which inverts the phase of Rtransmitted from an antenna port.
