Abstract
Provided is a reception apparatus that includes an in-phase-side mixer that mixes a high-frequency component and an in-phase-side local signal, and outputs the mixed signal as an in-phase-side mixed signal, a quadrature-side mixer that mixes the high-frequency component and a quadrature-side local signal orthogonal to the in-phase-side local signal, and outputs the mixed signal as a quadrature-side mixed signal, an error detection signal generation unit that generates four-phase detection signals having same frequencies as frequencies of the in-phase-side local signal and quadrature-side local signal, and each having a different phase, and a signal processing unit that generates a gain difference between an in-phase-side signal according to the in-phase-side mixed signal and a quadrature-side signal according to the quadrature-side mixed signal, on the basis of respective output signals of the in-phase-side mixer and quadrature-side mixer in a case where each of the four-phase detection signals is the high-frequency component.
