Abstract
A method is provided for estimating the focusing quality of a signal pre-equalized by time reversal of an estimated propagation channel between a source antenna of a source communicating entity and a destination antenna of a destination communicating entity, the method comprising a step of evaluating a focusing quality of the signal received at the destination antenna relative to a value at a focal point of a representation of a curve of received power as a function of a distance between the destination antenna and the focal point.
