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 10):
The radio communication apparatus according to  claim 8 , further comprising an IQ mismatch correction circuit configured to correct an IQ mismatch of an output of the analog digital converter and give the corrected output to the carrier leakage correction control circuit.
