摘要：
A system for diversity processing a signal propagated via two diversity antennas includes: respective propagation paths for propagating two replicas of the signal, these propagation paths being coupled to the two diversity antennas so that the replicas are propagated via different antennas; a time variable delay element for subjecting at least one of the replicas to a time variable delay; and a level adjusting element, such as an asymmetric splitter, to produce a level imbalance between the power levels of the replicas propagated via the two diversity antennas.
