摘要
PROBLEM TO BE SOLVED: To provide a calibration control device, a calibration signal generation device, an orthogonal conversion device and a demodulation device which can be flexibly adapted to various input signals and stably maintain suitable performance and characteristics at high levels without significantly changing configurations.;SOLUTION: A calibration control device for obtaining a frequency of a calibration signal to be overlapped on or alternative to two signals as a reference of compensation for deviation of both or one of orthogonality and a level of the two signals which are orthogonal to each other, includes frequency setting means for setting the frequency of the calibration signal for a frequency in a band in which a noise level is less than a predetermined value among bands to be occupied bands of the two signals.;COPYRIGHT: (C)2013,JPO&INPIT
