発明の名称 (英語) WIRELESS COMMUNICATION DEVICE AND OPERATION METHOD
発明の概要(英語) The present disclosure is a wireless communication device that is capable of reducing cost and size, and an operation method. A predetermined number of strain-compensation signals obtained by subjecting each of a predetermined number of input signals to a strain-compensation process that compensates for strain in a downstream non-linear circuit are up-converted at mutually different frequencies, synthesized, and then amplified and outputted as output signals. On the basis of these output signals, an adjustment unit for adjusting the strain-compensation process performed on the input signals performs a process for inverting the signal spectra of the input signals or feedback signals when the signal spectra is compared with the input signals that correspond to the frequency components of the feedback signals for which the signal spectra are inverted in conjunction with the output signals being down-converted in a feedback unit, the process being performed with respect to the frequency components. The present technique can be used, for example, in a wireless communication device provided with a strain compensation process.
