Reception apparatus, phase error estimation method, and phase error correction method
2014
The objective of the invention is to obtain a highly precise phase correction value even if a phase error or a noise level is large. In a phase error correction unit (9), a signal extraction unit (90) extracts received reference signals (GI) from received signals, and an error vector calculation unit (91) calculates the error vectors of phase errors by comparing the extracted received reference signals (GI) with a known reference signal that is to be transmitted. A representative vector calculation unit (92) divides, according to frequency, the error vectors into two or more groups and calculates representative vectors for the respective groups. A correction value calculation unit (93) calculates, on the basis of the representative vectors, phase correction values for the respective frequencies. A phase correction unit (94) uses the calculated phase correction values to correct the phase errors for the respective frequencies.
