Abstract
A filtering method, system, and equipment applied in digital communication technologies are disclosed in the embodiments of the present invention. The filtering method of the present embodiments includes: acquiring filtering coefficients of a part of all subcarriers according to data transmission errors; acquiring filtering coefficients of remaining subcarriers through an interpolation algorithm according to the filtering coefficients of the part of subcarriers; and finally, filtering the data corresponding to the multiple subcarriers according to the filtering coefficients of the part of subcarriers and the filtering coefficients of the remaining subcarriers. The part of subcarriers may be selected at a regular interval, or may be subcarriers which are located at a motion value away from the part of subcarriers selected in the previous update of the filtering coefficients. The method of the present embodiments reduces the amount of operation and hardware expenditure, and saves the cost.
