摘要：
An Orthogonal Frequency Division Multiplexing (OFDM) demodulator, an integrated circuit for OFDM demodulation and an OFDM demodulation method in which at least one side of a low order symbol filter interpolates the order of a low symbol direction and a high order symbol filter interpolates the order of a high symbol direction or suitably selects any of the weighting composite values to accomplish waveform equivalence of a carrier within outputted from a transform means based on the selection result.
