TERMINAL DEVICE, CHANNEL ESTIMATION METHOD AND INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a terminal device capable of separating propagation path of plural antenna ports even when using a virtual antenna to increase channel estimation accuracy.SOLUTION: A mapping section 103 maps a modulated data signal to a virtual antenna 0 and a virtual antenna 1 respectively. Between odd slots and even slots, a phase inversion section 104 synchronizes with a phase inversion section 105 to inverse the phase Stransmitted from an antenna port 2 and the phase inversion section 105 inverts the phase R0 transmitted from the antenna port 2; and a phase inversion section 113 synchronizes with a phase inversion section 114 to inverse the phase Stransmitted from an antenna port 3 and the phase inversion section 114 inverts the phase R1 transmitted from the antenna port 3.
