Channel Estimators

The following table provides an overview of the implemented channel estimators and indicates whether they exploit spatial, spectral/delay, or temporal properties of the channel.

For data-driven or statistics-based estimators, the corresponding doc page also documents how the estimators was trained/fitted.
