RECEIVER, RECEPTION METHOD, OFDM DEMODULATOR, PROGRAM AND COMPUTER-READABLE RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide an OFDM (Orthogonal Frequency Division Multiplex) demodulator capable of eliminating dependency of a manufacturing process and correcting a frequency error. SOLUTION: The OFDM demodulator 100 receives digital broadcast waves and performs sampling on the basis of the clock signal of a frequency oscillator different from a broadcast station. A frequency error detection part 106 detects a frequency error between a sampling frequency in OFDM modulation in the broadcast station and a sampling frequency in a sampling reception part 102. A sampling correction control part 107 calculates a fraction delay amount using the frequency error. A frequency error correction part 103 interpolates data at sampling timing in the broadcast station, which is true sampling timing, by filter processing from data sampled in the sampling reception part 102 on the basis of the fraction delay amount and corrects the frequency error.
