1. A CDMA receiver, comprising:

  • an SINR-estimation module configured for producing a plurality of pre-processed SINR estimates corresponding to a plurality of pre-processed symbol estimates from a received multipath signal, a thresholding module configured for comparing each of the plurality of pre-processed SINR estimates to a predetermined threshold for determining whether to employ a weighted soft decision or a hard decision, a companding module configured for generating the weighted soft decision or the hard decision for each of the plurality of pre-processed symbol estimates, and a canceller configured for producing at least one interference-cancelled signal corresponding to at least one multipath signal.
