An apparatus for reducing multiple access interference between received communication signals in a communication system having a base station and a plurality of user stations that exchange communication signals between the base station and each of the plurality of user stations. The apparatus comprises first means for selecting a first signal from a plurality of received code division multiple access signals, first means, coupled to the first selecting means, for estimating a confidence level of a correctness of the first signal, first means, coupled to the first estimating means, for reconstructing a first replica of the first signal, first means, coupled to the first reconstructing means, for determining a weight for the first signal based on the estimated confidence level to provide a first subtractive signal and first means, coupled to the first determining means, for subtracting the first subtractive signal from the plurality of received code division multiple access signals.
