Abstract
A method includes, in a mobile communication terminal, storing a mathematical model for computing a covariance matrix of data conveying signals that are received at the mobile communication terminal. At least a first data conveying signal is received in the mobile communication terminal, and one or more signal components required by the model are extracted from the first data conveying signal. A determination is made whether the model is suitable for computing the covariance matrix for the first data conveying signal based on a predefined rule. The covariance matrix is computed in the mobile communication terminal using at least one of the model and an empirical-based estimation of the covariance matrix. The covariance matrix is selected in response to the determination.
