摘要 |
A receiver apparatus receiving a quadrature-modulated, modulated wave, includes: a real-zero signal generator for adding a sinusoidal wave to the modulated wave to generate a real-zero signal; an in-phase and quadrature component detector for extracting an in-phase component signal and a quadrature component signal from the real-zero signal; a real-zero sequence generator 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 for reproducing the in-phase component and quadrature component from the real-zero sequence. It is possible to provide a receiving apparatus 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. |
