Title:
WIRELESS COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/193641
Kind Code:
A1
Abstract:
A wireless communication device (100) according to the present invention is characterized by being provided with a calibration signal generation unit (1) for generating a first signal for which the power spectrum on a frequency axis is comb-shaped, a quadrature modulation unit (4) for modulating the first signal, an inverse system identification unit (8) for identifying an inverse system of the quadrature modulation unit using the first signal, and an inverse system unit (9) for correcting distortion occurring in the quadrature modulation unit using the identified inverse system, and furthermore is characterized in that the first signal is orthogonal to a signal in which the frequency of the first signal is inverted.
