Abstract:
A carrier leakage correction method for a quadrature modulator according to an embodiment includes inputting a test signal with a frequency f BB  to a transmitter and up-converting the test signal with a frequency f L0  and down-converting with the frequency f L0 . A frequency 2f BB  component is detected in the down-converted test signal. One or a plurality of parameters of the transmitter is/are adjusted so as to reduce a magnitude of the detected frequency 2f BB  component in the test signal.

Claim (Index 1):
A radio communication apparatus comprising:\n a carrier leakage correction circuit configured to correct a carrier leakage of a test signal of a first frequency, based on one or more correction parameters; a quadrature modulator configured to up-convert the test signal with a second frequency; a quadrature demodulator configured to down-convert the up-converted test signal with the second frequency; and a carrier leakage correction control circuit configured to detect a frequency component twice the first frequency from the down-converted test signal, and adjust the one or more correction parameters to be given to the carrier leakage correction circuit so as to reduce a magnitude of the detected frequency component twice the first frequency.
