Abstract

The invention has the object of determining the optimum weighting coefficient for each channel in a subtractive interference canceller (IC). A weighting coefficient determining method in a subtrative interference canceller for handling digital radio communications, characterized in that complex weighting coefficients are set so as to minimize the power of an interference cancellation residual signal for each channel in each stage.
