Orthogonal beam codebook based hybrid precoding algorithm for mmWave MIMO system by Weiting ZHAO, Dongliang XIA

“…Due to the high cost and power consumption of some mixed signal components at mmWave frequencies,the conventional full digital precoding technique encounters the problem of high hardware complexity.Consequently,the hybrid analog-digital precoding architecture has attracted the attentions from both academy and industry.Based on this,an orthogonal beam codebook based hybrid precoding algorithm for mmWave MIMO systems was proposed,which utilized the orthogonality of beam codebook to design the analog beamforming vector of each radio frequency (RF) chain in parallel.As a result,the large computational complexity of the conventional orthogonal matching pursuit (OMP) algorithm and the hardware complexity could be greatly reduced.…”

Motion Control Modeling and Simulation of the Thruster Mechanism of a Boring Machine by Wang Shuanghua, Wang Jianwei

“…The thruster mechanism of which two neighboring thruster cylinders are wedge-shape arranged is a redundant driving multi-DOF parallel mechanism.It is very complex to control its motion due to the complexity of the mechanism and the coupling between the driving rods,so a method of establishing inverse kinematics model of the thruster mechanism and graphical model with the SimMechanics in the environment of Simulink diagram design in MATLAB is presented and then connect them by controller.The trajectory tracking control of parallel mechanism is realized and this method is intuition and convenience.A foundation for the precious control of thruster mechanism is laid and it is provide convenience for establishing simulation models of other multi-body dynamic system.…”
