1. A CDMA receiver, comprising:

  • a signal-to-interference-and-noise ratio (SINR)-estimation module in a receiver, the SINR estimation module configured for producing one or more SINR estimates corresponding to one or more subchannels of a received multipath signal;

    a thresholding module configured for comparing each of the one or more SINR estimates to a threshold to determine 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 determined by the thresholding module for each of the one or more SINR estimates; and

    a suppressor configured for producing at least one interference-suppressed signal from one or more of the soft decisions or hard decisions generated by the companding module.
