Reference [1] Andreas F. In massive MIMO systems, hybrid beamforming is an essential technique for exploiting the potential array gain without using a dedicated RF chain for each antenna. The example employs full channel sounding for determining the channel state information at the transmitter. Previously. txt) or read online for free. For example, in FDD massive MIMO, the uplink channels can be mapped to the downlink channels or the downlink channels at one subset of antennas can be mapped to the downlink channels at all the other antennas. pdf - Free download as PDF File (.
