摘要： A composite signal including a plurality of component signal streams is processed using QR-decomposition to detect symbols and calculate a decision metric for each of the signal streams (202). Soft serial interference cancellation is performed on the composite signal based on the symbols detected for different ones of the signal streams and a ranking of the signal streams (204). The symbols are re-detected and the decision metric re-calculated for each signal stream based on soft serial interference cancellation results (206). The different decision metric calculations for at least one of the signal streams are compared to determine whether symbol detection is more accurate with or without soft serial interference cancellation (208). The signal streams are decoded using symbols detected based on soft serial interference cancellation results when symbol detection is determined to be more accurate with soft serial interference cancellation (210). Otherwise, the streams are decoded based on the symbols detected using QR- decomposition (210).

摘要： A subset of modeled impairment correlation terms are selected for use in received signal processing. According to one embodiment, a subset of modeled impairment correlation terms is selected and a composite impairment correlation term is determined based on the subset of modeled impairment correlation terms. The composite impairment correlation term may be determined by scaling the modeled impairment correlation terms included in the subset by respective model fitting parameters. The scaled modeled impairment correlation terms are then combined to form the composite impairment correlation term. The subset of modeled impairment correlation terms may be selected based on their respective model fitting parameters. In one embodiment, the modeled impairment terms having a model fitting parameter that satisfy a threshold are included in the subset while those that do not are excluded. The composite impairment correlation term may be used for received signal processing, e.g., demodulation or signal-to-interference estimation.
