Overview of Precoding Techniques for Massive MIMO
Massive multiple-input multiple-output (MIMO) is playing a crucial role in the fifth generation (5G) and beyond 5G (B5G) communication systems. Unfortunately, the complexity of massive MIMO systems is tremendously increased when a large number of ...

A Low Complexity Precoding Algorithm for Large-scale MIMO System [PDF]
In large-scale Multiple-Input Mutiple-Output(MIMO) system,the increase in the number of antennas and users on the base station side leads to an increase in the dimension of the channel matrix,which increases the computational complexity of the precoding ...

Constellation Precoded Beamforming [PDF]
We present and analyze the performance of constellation precoded beamforming. This multi-input multi-output transmission technique is based on the singular value decomposition of a channel matrix. In this work, the beamformer is precoded to improve its diversity performance.

Design of hybridly-connected hybrid precoding in millimeter-wave massive MIMO system
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
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 ...
