<P>PROBLEM TO BE SOLVED: To provide the carrier leak adjusting device of an orthogonal modulator which can sufficiently adjust a carrier leak even if a detection output changes. <P>SOLUTION: A control circuit (CTRL) 9 specifies a correction signal (correction amount) supplied to an adder 1 and an adder 4 on the basis of the carrier leak measured by a detector 7. At the time, a signal of correction value candidate is changed in every specified step, the correction value is specified, and the excess carrier leak amount measured by the continuing correction value candidate is evaluated as an index of the reliability of the data. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
