Synchronization is ensured in a receiving unit between received DS-CDMA coded multipath signals and a provided code, which signals are provided to a plurality of Rake fingers 1, 2. Each of the Rake fingers correlates received signals of a multipath associated to the respective Rake finger with the provided code. In order to enable a reduction of interferences between the multipaths, it is proposed that for each Rake finger an interference from signals of multipaths associated to the other Rake fingers is estimated, based on characteristics of pulse shaping filters employed by a transmitting unit and the receiving unit, on estimated propagation delays on the multipaths and on the correlation results in the Rake fingers. The method further comprises subtracting the respective estimated interference from the correlation result in the corresponding Rake finger. The invention relates equally to a corresponding software, ASIC and receiving unit.
