A communication terminal is described comprising a receiver configured to receive pilot signal samples via a plurality of communication channels and to determine an interference matrix which includes, for each pilot signal sample, interference information representing an amount of interference included in the pilot signal sample and a channel estimator configured to determine a channel autocorrelation matrix for the plurality of communication channels and to determine a linear transformation which diagonalizes or triagonalizes the autocorrelation matrix, to transform the interference matrix by the transformation and to reduce the transformed interference matrix by discarding components corresponding to predetermined eigenvectors of the autocorrelation matrix, to determine filter weights for the signal samples based on the reduced interference matrix and to determine channel estimates by filtering the pilot signal samples using the determined filter weights.
