A Low Complexity Precoding Algorithm Based on Parallel Conjugate Gradient for Massive MIMO Systems
IEEE Access, 2018 Linear precoding algorithms with low complexity in massive multi-in multi-out system have always been a hot research topic to solve the problem of inter-cell interference. In this paper, we proposed a conjugate gradient-based regularized zero-forcing (CG-

Frequency-domain precoding for single carrier frequency-division multiple access [PDF]
, 2009 At present there is considerable interest in the use of single carrier frequency-division multiple access. This interest is justified by the inherent single carrier structure of the SC-FDMA scheme, which is more robust against phase noise and has a lower

Hybrid precoding method for mmWave MIMO systems based on limited feedback
Dianxin kexue, 2018 A hybrid precoding algorithm for millimeter wave (mmWave) MIMO systems without knowledge of channel state information at the transmitter was proposed based on the limited feedback.Specifically, the joint optimization problem of analog precoding and ...

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 ...
