Abstract
A method and apparatus carry out received signal processing for received communication signals based on least squares processing to estimate the contribution of one or more interferer signals. The exemplary receiver uses interferer signal channel estimates to obtain least squares estimates for the interference contributions of one or more interferer signals, and then uses those estimates to suppress interference during demodulation processing. Further, the least-squares estimates may be used to obtain a reduced search space wherein the candidate set of signals searched during demodulation processing is reduced.
