The auxiliary channel estimating process based on pilot signal is introduced,and a model for the auxiliary channel is presented according to the process. A modified algorithm is proposed by analysis of the channel interpolation estimating method.In this method a phase rotation factor is multiplied to the channel response of pilot signal in order to eliminate phase shifting effect introduced by the interpolation method.
