Abstract: A receiver apparatus 200 receiving a quadrature-modulated, modulated wave, includes: a real-zero signal generator 205 for adding a sinusoidal wave to the modulated wave to generate a real-zero signal; an in-phase and quadrature component detector 206 for extracting an in-phase component signal and a quadrature component signal from the real-zero signal; a real-zero sequence generator 207 for generating a real-zero sequence as a sequence of time points at which the in-phase component and quadrature component signals become zero; and a signal reconstruction unit 208 for reproducing the in-phase component and quadrature component from the real-zero sequence. With this, it is possible to provide a receiving apparatus etc. that enables decoding of a received signal with high precision even when sufficient linearity cannot be secured in the analog circuit of the receiver apparatus.
