Interference signal eliminator

摘要

Matched filters 102-1 to 102-n extract channel estimated values corresponding to users 1 to n by finding correlation with the reception signal. Threshold processing sections 103-1 to 103-n perform threshold processing on estimated power values obtained based on the channel estimated values corresponding to users 1 to n. JD section 104 performs matrix calculations using channel estimated values subjected to threshold processing. Multiplication section 105 performs a multiplication between the matrix calculation result and the reception signal. Identifier 106 performs hard decision on the multiplication result.
