摘要：
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.
摘要（中）：
接收正交调制调制波的接收机装置200包括：实零信号发生器205，用于将正弦波加到调制波以产生实零信号; 用于从实零信号中提取同相分量信号和正交分量信号的同相和正交分量检测器206; 用于产生实零序列作为同相分量和正交分量信号变为零的时间点序列的实数零序发生器207; 以及用于从实零序列再现同相分量和正交分量的信号重构单元208。 由此，即使在接收装置的模拟电路中不能确保足够的线性度的情况下，也能够提供能够高精度地对接收信号进行解码的接收装置等。
