The invention relates to a method for reducing the effects of noise and to a receiver comprising at least one sampling means (12) for forming sample signals from a received signal. The receiver also comprises a whitening means (30) for converting the noise in the sample signals to white noise and digital filters (41, 42, 43, 44) for filtering the sample signals comprising white noise. The receiver further comprises a computation means (80) for computing filter tap coefficients from a sample signal. Further still, the receiver comprises summers (51, 52), each one of which is arranged to receive a filtered signal from at least one filter and to sum the signals received from the filters to produce first summed signals. The receiver also comprises a detector (60) for summing the first summed signals to produce the actual summed signal and for detecting the actual summed signal.
