OFDM communications apparatus, OFDM communications method, and OFDM communications program

摘要

An object of the present invention is provide an OFDM communications apparatus for achieving a phase correcting a highly-accurate phase correcting process which does not gradually lose accuracyor requiring large hardware. An Arctan vector phase rotator 104 calculates a phase of a vector signal. A phase correction information estimator 105 finds an estimated multipath-fading deviation value from the phase of a vector in a phase error estimation symbol 207, and also finds an estimated non-multipath-fading deviation value from the phase of a vector in a pilot signal 209. An adder 106 adds these two estimated deviation values together for output as a total phase correction value. Based on the total phase correction value, the Arctan vector phase rotator 104 rotates the phase of a vector to be demodulated for phase correction.
