OFDM receiver and method for correcting multipath phase deviation using a training sequence and for performing carrier and clock recovery using pilot symbols

摘要

An object of the present invention is to provide an OFDM communications apparatus for phase correction which does not gradually lose accuracy or require a complex hardware. An Arctan vector phase rotator (104) calculates a phase of a received vector signal. A phase correction information estimator (105) calculates both an estimated multipath-fading deviation value from the phase of a vector in a training symbol, and a non-multipath-fading deviation value from the phase of a vector in a pilot signal. 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 (107) for phase correction.
