Abstract

Based on distribution information of interference signal in signal sequence, the invention sets up sequence of weight value. Weighting process is carried out for signal sequence or sequence of local code to calculate relevant result. The normalization process is carried out for the said relevant result. The method takes full advantage of information of interference signal in signal sequence and sets up weighting value smartly so as to reach purpose of lowering received interference. Features of the method are simple and easy of implementation.
