Abstract
A system for implementing a transmit uplink channel in MIMO RDN architecture is provided herein. The system includes a multiple-input-multiple-output (MIMO) transmitting system that includes a MIMO baseband module having N branches; and a radio distribution network (RDN) connected to the MIMO receiving system. The RDN includes at least one beamformer, wherein each of the beamformers feeds K transmit antennas, so that a total number of transmit antennas in the system is M=N*K. At least some of the beamformers include passive splitters/combiners configured to split the signal coming from the transmitter into multiple signals which are weighted individually going to each transmit antenna. The baseband module is configured to repeatedly apply a 'blind scanning' process to at least some of the transmit antennas, one at a time, so that performance of the tested transmit beam can be graded.
