Method and device for cross-polarization interference suppression

A method (1100) for cross-polarization interference power suppression in dual-polarization radio communication systems includes: filtering (1101) a vertical polarization component (xV(n)) and a horizontal polarization component (xH(n)) of a received dual-polarization channel signal by a 22 channel weights matrix (507, 508); and determining (1102) the 22 channel weights matrix (507, 508) based on a minimum variance distortionless response criterion.
