SpletThe second adds beamforming capabilities with a discrete-time vector-modulator phase shifter, based on sampling region switched-RC loops. The third design evolves the … Spletthe DL-based analog beamforming and hybrid beamforming schemes. However, these DL-based beamforming schemes require perfect explicit CSI, which can be difficult to obtain in FDD massive MIMO with fully-digital array and TDD/FDD massive MIMO with hybrid array. To this end, some DL-based beamforming schemes that only require implicit CSI were ...
