| 1. A method of determining received signal impairment correlations using a model for impairment correlations comprising one
or more model impairment terms scaled by corresponding model fitting parameters, the method comprising:
computing the one or more model impairment terms;
measuring received signal impairment correlations;
adapting each of the model fitting parameters using a fitting process to fit the modeled impairment terms, as scaled by the
model fitting parameters, to the measured received signal impairment correlations; and
calculating the modeled impairment correlations based on the adapted model fitting parameters.
