Abstract
A well known problem of regularization (diagonal loading) of the interference rejection combining (IRC) and IRC / maximum ratio combining (MRC) switching is addressed. Different empirical loading factor selection rules adjusted to specific scenarios have been introduced in the literature. It is expected that future network will be characterized by variety of scenarios, transmission modes, and receiver configurations. Empirical IRC regularization may not be suitable for such networks. In this study we consider the Expected Likelihood (EL) criterion for estimation/selection of the interference plus noise covariance matrix and demonstrate that it gives the diagonal loading selection rules that are effective in wide range of scenarios and receiver configurations.
