Abstract
A system for transmitting a signal via diversity antennas includes at least one delay element for generating at least one delayed replica of the signal subject to a given delay, the signal and the at least one delayed replica being adapted to be transmitted via the diversity antennas, and a control unit for the at least one delay element for varying the given delay, whereby the signal and the at least one delayed replica, transmitted via the diversity antennas, give rise to alternate constructive and destructive combinations therebetween.
