Abstract
A system for distinguishing between any one of a plurality of antennas in a multiple-input-multiple-output (MIMO) system having an augmented number of antennas is provided herein. The system includes a MIMO receiving system having N branches and configured to operate in accordance with a channel estimation MIMO receiving scheme; a radio distribution network (RDN) connected to the MIMO receiving system, the RDN comprising at least one beamformer, being fed by two or more antennas, so that a total number of antennas in the system is M, wherein M is greater than N, wherein each one of the beamformers include a combiner configured to combine signals coming from the antennas into a single signal; and at least one antenna distinguishing circuitry, each associated with a respective beamformer, wherein the antenna distinguishing circuitry is configured to distinguish between the signals coming from the antennas which feed the respective beamformer.
