RADIO COMMUNICATION DEVICE AND RADIO COMMUNICATION METHOD |
摘要 |
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 (103) which maps a data signal after modulation to a virtual antenna (0) and a virtual antenna (1); a phase inversion unit (104) which inverts the phase of S0 transmitted from an antenna port (2) in synchronization with a phase inversion unit (105) between the odd-number slot and the even-number slot; the phase inversion unit (105) which inverts the phase of R0 transmitted from the antenna port (2); a phase inversion unit (113) which inverts the phase of S1 transmitted from an antenna port (3) in synchronization with a phase inversion unit (114); and the phase inversion unit (114) which inverts the phase of R1 transmitted from an antenna port (3). |
