Abstract
The present invention relates to a node in a wireless communication system (W), the node comprises an antenna arrangement with at least three physical antenna elements and a first beam-forming network. Each physical antenna element has a corresponding physical phase center and antenna port. The physical phase centers are separated by corresponding physical distances, and the physical antenna ports are connected to the first beam-forming network. The first beam-forming network is arranged to transform the physical antenna ports to at least two virtual antenna ports which correspond to virtual antenna elements. Each virtual antenna element has a certain virtual phase center where the virtual phase centers are separated by corresponding virtual distances, where the physical distances differ from the virtual distances. The present invention also relates to a corresponding method.
