PHASE NOISE CORRECTION CIRCUIT, TRANSMISSION DEVICE, RECEPTION DEVICE, RADIO DEVICE, RADIO COMMUNICATION SYSTEM, AND PHASE NOISE CORRECTION METHOD

摘要

An object of the present invention is to sufficiently exhibit carrier reproduction performance in a radio device having a transmitter and a receiver and performing radio communication. A phase noise correction circuit provided in the transmitter in the radio device includes: a phase error information acquisition unit that acquires phase error information detected by a receiver of the radio device; and a phase noise correction unit that performs correction of phase noise generated by a local oscillator shared between the receiver and transmitter for a baseband signal upon radio transmission by using the phase error information acquired by the phase error information acquisition unit.
