A multi-user receiver which uses at least two antenna elements and in which the influence of interference is reduced, the receiver comprises: means ( 200 ) for pre-filtering a wideband antenna signal, the pre-filtering means being determined on the basis of a spatial covariance matrix estimate, which spatial covariance matrix estimate is obtained from wideband antenna signals by sampling, arranging sampled values into a signal vector and by multiplying the signal vector by its conjugate transpose vector, means ( 210, 218 ) for removing the whitening from signals of predetermined users by using an inverse matrix of the matrix used in the whitening filter, means ( 202, 204, 206, 208, 210 ) for performing multi-path combining and multi-antenna combining.
