Design of hybridly-connected hybrid precoding in millimeter-wave massive MIMO system
Tongxin xuebao, 2020 In order to improve the spectral efficiency of hybridly-connected hybrid precoding,the optimal hybrid precoding matrix under the ideal conditions was firstly obtained by using the principle of successive interference cancellation (SIC).Secondly,the ...

Beamforming and precoding techniques
, 2020 Beamforming and precoding/combining are techniques aimed at processing multiantenna signals at the transmitter and/or at the receiver of a wireless communication system. While they have been routinely used to improve performance in current and previous generations of mobile communications systems, they are expected to play a more fundamental role in ...

On equivalence of SLNR-based precoding and RBD precoding
Electronics Letters, 2012 Signal-to-leakage-plus-noise ratio (SLNR) based precoding and regularised block diagonalisation (RBD) precoding are two notable linear precoding schemes in downlink multi-user multiple-input multiple-output (MIMO) systems. The equivalence of these two precoding schemes is demonstrated.
