Abstract A method of estimating the half-blind channel, deep attenuation, resistant is provided in wide band code division multiple access. The invention estimates channels by using the data information of the data channel e.g. with the method of identifying blind subspace, at the deep attenuation position and estimates channels with the pilot frequency information of the pilot frequency channel at the position beyond those mentioned above. This invention can solve the problems caused by deep attenuation in channel estimation, so as to make correct estimation of the channels when the mobile station moves fast.
