OFDM RECEIVER

摘要

PURPOSE: An OFDM receiver is provided to improve the equalization efficiency without an extra pilot signal by equalizing OFDM symbols in a frequency domain by using fourier-transformed information of synchronous information. CONSTITUTION: A demultiplexer(31) separates orthogonal frequency division multiplexing(OFDM) equalized in a time domain for outputting a plurality of signals. A first inverse discrete fourier transform(IDFT) unit(32) transforms synchronous information which are information set between transmitting and receiving sides. A second IDFT unit(33) transforms OFDM effective symbols among the plurality of signals. A frequency domain equalizer(40) equalizes the transformed OFDM effective symbol in a frequency domain based on the fourier-transformed synchronous information.
