The invention provides a new method to reduce the common phase error carried by the multi carrier modulation symbol receiver receive the estimated phase error is determined by one or a plurality of modulation symbols value, average value estimation and calculation of one or more phase error values, to the average value as an estimate of common phase error values of phase compensation of each modulation symbol of public. Because the invention estimates the modulation symbols by general transmission and receiving device known phase pilot signal or transmission parameter signaling to common phase error and therefore less affected by multipath effects, estimation of the common phase error accurately, effectively reduce the bit error rate of the system. In addition, the invention further estimates, due to the modulation symbol interference to the public small phase error, phase error estimation of the public more accurate, more effectively reduces the error rate of the system.
