Abstract:
1. A CDMA receiver, comprising: an signal-to-interference-and-noise ratio (SINR)-estimation module in a receiver, the 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, a synthesizer configured for producing a synthesized interference signal from an output of the companding module, wherein the synthesizer comprises a channel emulator configured for providing channel distortions to the synthesized interference signal, and a canceller configured for producing at least one interference-cancelled signal from an output of the channel emulator.
