METHOD FOR DYNAMICALLY CONTROLLING FOCUSING OF A TIME-REVERSAL PRE-EQUALIZED SIGNAL

摘要

Method of dynamic control of the focusing of a signal pre-equalized by time reversal of an estimated propagation channel between an original antenna (A1) of an original communicating entity (EC1) and a destination antenna (A2) of a destination communicating entity (EC2) at a current instant, the method comprising the steps of evaluation by the destination communicating entity of a relative quality of focusing (Q(n)) of the pre-equalized signal emitted by the original antenna and received by the destination antenna, with respect to a quality at a focal point (FO), and if the evaluated relative quality of focusing does not satisfy a predetermined criterion, of requesting, by the destination communicating entity, of modification of focusing to the original communicating entity for a following instant.
