DOI: 10.1109/tvt.2020.3042198
Abstract: Massive capacity gain in Massive MIMO (multiple-input and multiple-output) depends on uplink pilots sent by the users to provide up-to-date CSI (channel state information) for closed-loop precision beamforming. To support a huge number of IoT… read more here.
