RECEIVER, RECEPTION METHOD, AND INFORMATION RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a receiver or the like suitable for transmission of a data signal whose length ratio to the length of a known signal is large. SOLUTION: A reception signal 201 outputs a reception signal 102, an estimate section 202 estimates a propagation characteristic 103 on the basis of the reception section 102 and a modulated data signal 106, a compensation section 203 outputs a compensated data signal 104 from the reception signal 102 and the propagation path characteristic 103, a demodulation section 204 demodulates a demodulated data signal 105 from the compensated data signal 104, and a modulation section 205 modulates the modulated data signal 106 from the demodulated data signal 105. The estimate section 202 compares the modulated known data with a known data part of the reception signal to start estimation and the compensation section 203 uses the propagation path characteristic that is estimated to compensate a data signal part not compensated.
