Abstract
Residual phase error compensation circuit 104 performs differential detection between pilot symbols included in an OFDM signal to compensate for residual phase errors of the OFDM signal and then propagation distortion compensation circuit 105 compensates for propagation distortion of the OFDM signal using the re-coded signal as a known signal.
