1. A receiving device comprising:

  • a radio receiving unit to receive radio signals transmitted from a plurality of transmitting antennas by a plurality of receiving antennas and output received signals being digital signals;

    a frequency control unit to detect a frequency error contained in the received signals and correct the frequency error;

    a channel estimation unit to estimate a channel matrix of which each element corresponds to respective pair of each transmitting antenna and each receiving antenna;

    an equalization unit to equalize the received signals by using the channel matrix estimated by the channel estimation unit;

    a demodulation and decoding unit to demodulate and decode the received signals equalized by the equalization unit; and

    an error estimation unit to estimate a channel variation component indicating temporal variation of characteristics of each channel and a phase error component remaining in the received signals based on the channel matrix, the received signals, and a decoding result by the demodulation and decoding unit or an equalization result by the equalization unit.
