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 8):
The radio communication apparatus according to  claim 1 , further comprising:\n a digital analog converter configured to convert an output of the carrier leakage correction circuit to an analog signal, and give the analog signal to the quadrature modulator; and an analog digital converter configured to convert an output of the quadrature demodulator to a digital signal, and give the digital signal to the carrier leakage correction control circuit, wherein the carrier leakage correction circuit is configured to output the test signal which is digital in which the carrier leakage is corrected.
