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 2):
The radio communication apparatus according to  claim 1 , wherein the quadrature modulator is configured to increase a distortion component of the up-converted test signal and give a resultant test signal to the quadrature demodulator.
