ORTHOGONALITY COMPENSATING DEVICE, RADIO RECEIVING DEVICE, ORTHOGONALITY COMPENSATING METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM

摘要

Provided is an orthogonality compensating device that compensates for orthogonality between a real signal and an imaginary signal of complex digital intermediate frequency signals, the orthogonality compensating device including: a first processing unit that outputs a first signal obtained by calculating one of the real signal and the imaginary signal by using a first coefficient and a second coefficient; and a coefficient specifying unit that specifies the first coefficient such that the first signal has the same amplitude as the other of the real signal and the imaginary signal, and specifies the second coefficient such that the first signal is orthogonal to the other of the real signal and the imaginary signal, by using the first signal and the other of the real signal and the imaginary signal.
